Hello,
I need the ESD rating test date for the following two devices:
ADR5040BKSZ-REEL7
ADR5041BKSZ-REEL7
I also would like to know what test standard(s) is used for ESD qualification? Is there a link to the information? A manual?

What is TECGAIN of ADN8834 DS?
Hi,
I have a question about TEC controller ADN8834.
I can see an equation of f_0dB in DS at p18.
Can you explain what TECGAIN in it?
from Fig 35, 0dB should be at 1/(2*pi*R_1*C_1). But f_0dB of equation has x(R_FB/(R_TH + R_x) - R_FB/R)xTECGAIN.
I assume the followings;
1. TECGAIN is a varied value from device itself. It can change by hot mode or cold mode.
2. When users think of PID Compensation, they can ignore x(R_FB/(R_TH + R_x) - R_FB/R)xTECGAIN. The part would be canceled as x1 or very tiny???
Is my assumption correct?
If not, could you explain what it is?
I would like to know
- What is TECGAIN? and how can it be led in calculation?
- Why is x(R_FB/(R_TH + R_x) - R_FB/R)xTECGAIN ignored in Fig 35?
Thank you for your help.

AD5522 can not communicate via SPI?
Hi All:
I have a AD5522 Evaluation Board,and it's work well on Evaluation Software 1.6.1.
Now I want to use my STM32F103ZE to control the AD5522,but I can't communicate with AD5522 via SPI.
It's Evaluation Software timing,I want to read system control register,so I click READ SYSTEM CONTROL REGISTER ,and then, the software will send 0x10000000 to AD5522,and AD5522 will return 0x00000020 to me, it's work well in anytime.
Write 0x10000000
Read 0x000020 (Default value when AD5522 power on)
Now,I want to use my STM32F103ZE to read system control register,so I connect STM32F103ZE and AD5522,and remove the LK9 to disable USB function.As show below picture.
The first time,STM32F103ZE will send the command 0x10000000 to AD5522,that meaning read system control register
And then,STM32F103ZE will send 0xFFFFFF try to read data from AD5522, but the Busy pin goes low when 19th rising clock edge of SPI-CLOCK? Even so the result is 0x000020,that is true.
But the second time,STM32F103ZE send the command 0x10000000 to AD5522 again,the Busy pin goes low when 5th rising clock edge of SPI-CLOCK and 31th rising clock edge.
And then ,result is 0x000000,that's wrong(0x000020 is true).
Simulation SPI Code:
uint32_t AD5522_SPI(uint16_t bits, uint32_t dat)
{
uint32_t Recvice = 0;
uint8_t i;
AD5522_CS_L;
AD5522_Delay(2);
//bits = 32 when write data to AD5522 and bits = 24 when read data from AD5522
for(i = 0; i < bits; i++)
{
if(dat & 0x80000000) //MSB
{
AD5522_MOSI_H;
}
else
{
AD5522_MOSI_L;
}
//CLOCK High
AD5522_CLK_H;
dat <<= 1;
Recvice <<= 1;
AD5522_Delay(1);
AD5522_CLK_L;
if(AD5522_MISO) //Read data when CLOCK falling edge.
{
Recvice++;
}
AD5522_Delay(3)
}
AD5522_Delay(1);
AD5522_CS_H;
AD5522_CLK_L; //Idle time,CLOCK is low
AD5522_MOSI_L; //Idle time,MOSI is low
return Recvice;
}
This problem puzzle me three days,can you help me?
sorry for my bad English.
thanks.

Hi,
VisualAudio is a very good program for developing audio application using ADSPs. A separate category for it must be very popular.

About how to use ADN2818
So I'm outsider of SONET, I query you about foundamental usage of ADN2818.
Q1.I want to use it as clock and data separater from "enbedded clock signal" like a 8B10B.
If it possible,
Q2.Dose it can receive long run length for example 20UI?
#By the way, I'm a beginner to EngineerZone.
Dose the discuccion suit there category?

ADN8834, Amplifers
Hallo,
are the two chopper stabilized amplifers inside the ADN8834 on while the chip is in standby. I plan implementing a digital control loop arournd the AD8834. It want to use one of the amplifiers for buffering the voltage across the thermistor. But I want to measure temperature without activation the power stage.

application ADN2841
Hello!
I am going to use ADN2841 in my design, but I have got some questions.
1. The ADN2841 is very good for our conditions, but it has a small current of modulation. I have got a laser diode module with current of modulation in range 400 - 600 mA. Can I to apply the ADN2841 with my laser? Have you any got application for my problem?
2. What logic levels have the Differential ports Data and CLK in the ADN2841?
Thank you.

AD5520:trouble with MEASOUT voltage range
HI this is my sch of ad5520. the pin 64(CLL) vee_3v3 is -3.3V and pin 63(CLH) vcc_3v3 is +3.3v.
I change the pin 26(FIN) voltage , the pin 58 (MEASOUT) should from -3.3V to + 3.3V . but the pin 58 (MEASOUT) is -0.256V to 3.3V.
the R74 is 100K. and in force current mode
why the pin 58 (MEASOUT) is -0.256V to 3.3V.

Question about test setting of ADN8834
Hello,
My customer wants to confirm the performance of ADN8834 using EVM first.
And they are trying to test a ADN8834 EVM and TOSA module with Thermoelectric Cooler (from NeoPhotonics.)
During the test, they say that they can't confirm TEC currents, they can confirm only small change of TEC currents occasionally.
So they request how to confirm the operation of ADN8834 and how to set up ADN8834 at temperature test.
(They use plat cable for connecting between ADN8834 in EVM and TEC in TOSA module.)
Would you advise me how to test ADN8834 in EVM ?
If you have any questions, please let me know.
Rgerads,

ADCMP572 VTT pin confusion
We've received 2 ADCMP572 eval boards, but unfortunately the documentation for the part and the eval board seems to be inconsistent.
As a result, I have a question: should VTT (pin 8) be tied to GND or pulled high?
Per the part datasheet (pg. 6) it should be tied to VCCO, but on the eval board it is jumpered to the ground plane (APLANE) via P3, and that is listed as being the correct jumper setting (pg. 9).
Thanks.

Simulation software and a library for ADN3000-06 ic
I am a university student doing my final year university project.Part of My project is to design a fiber optic receiver.I am employing Analog devices ADN3000-06-50A-PT7 ic for this purpose.I am encountering several issues with the ic ...
1) First question i have is this ic is in die form,therefore it is hard to solder for undergraduates like us.So do you have this ic as a chip with a package?
2)Do you have footprints available for this ic,if so please guide me how to get a footprint?
3)I am planning to design the application for about 3Gbps.I have to design circuit and simulate by a software first.What is the simulation software that can be used for a RF design like this?Does Analog devices has a library created for ADN3000-06 ic for this simulation software?
I would be really grateful for your supports to fix my above mentioned issues...
Thank you

ADF7021 Daughter board ADF7021DBZ5
Hi,
I have this daughter board (ADF7021DBZ5) which i will stream to 144 MHz, then my question is, which components I need on this board to transmit at the desired frequency?, Since this board does not come with the necessary components to transmit.
In the application note AN-859 there are a components of the band 140-150 MHz, but on page 10 is the use of an XTAL of 11.0592 MHZ and ADF7021DBZ5 board comes already connected to 19.680 MHz XTAL.
So my question is: which components they need connect on this card to transmit a 144 MHz to 19,680 MHz XTAL?

AD5522 Eval Board idle temperature
Hi,
My customer noticed that the AD5522 Eval Board run hot when idle(no load ,output disable) ca. 70°C
From the reference design, ADI does not mention any heat sink required .
Is this typical? I doubt that we can achieve the spec at that temperature.
Where can I get the thermal characteristic for the chip.
Thank you.

Questions on pins MIX_I, MIX_Q, FILT_I and FILT_Q for ADF 7020
Dear Sir/Madam,
My primary goal is to find the phase information of the received signal using a quadrature demodulation architecture receiver/transceiver. Therefore the signals I am most interested in are the I and Q signals at the output of the two down-conversion mixers since phase=arctan(Q/I) if my understanding is correct. From the data sheet of ADF7020, I learned that there might be several pins related to I and Q signals, i.e. MIX_Q, MIX_I, FILT_I and FILT_Q.
I wonder which pins I should use to fulfill my purpose here? Will I be able to obtain DC values for I and Q signals here?
Also, the datasheet indicates that these pins are high impedance pins and should be left open, how can I be able to monitor the signals from those pins?
Thank you so much in advance.

EVAL-ADF70XXMBZ2
hi,
May I ask for a copy of the source code of chip programming software which
display the data received by the EVAL-ADF70XXMBZ2 connected to a host PC transmitted by another EVAL-ADF70XXMBZ2 via RF
which Analog Devices created?
Both EVAL-ADF70XXMBZ2 contains EVAL-ADF7021DBZX daughter board.
I have replaced the existing ADXL322,a 2-axis intertial sensor, with ADXL330,a 3-axis intertial sensor, to one of the board that transmit data.
With this change I am planning to make a customized GUI displaying the new data.
Any suggestions on some helpful tools or software would be greatly appreciate.
