Part Number: ADS5409 My customer is having a problem with the temperature readback from the ADS5409.
They're accessing the ADC via its 3-wire SPI port and have no problem accessing other internal registers.
No evidence of a problem with the SPI.

Part Number: ADS5409ADS5409 has a SYNCp/n (LVDS differential pair) which forces the DDR output clock into a determinate state.
The datasheet (p.25) says that the SYNC signal is registered on the rising edge of CLKIN - the ADC sample clock.
Is there any…
Part Number: ADS5409EVM Other Parts Discussed in Thread: ADS5402EVM , ADS5409 The ADS5409EVM (same as ADS5402EVM) appears to be driving the ADC’s SCLK, SDIO, and SDENB pins with 3.3V levels in violation of the ADC’s absolute maximum input voltage levels…
Part Number: ADS5409 Hi Team,
I have a question that I'd like to get your help on regarding the ADS5409.
My customer is wondering if applying a differential signal less than 3.3V to the input pins before its supply voltage rails come up has the potential…
Part Number: ADS54J20 Other Parts Discussed in Thread: ADS5409 , LMK04828 Hi Team,
My customer is working on a new design that uses one ADS5409 and one ADS54J20. They are clocking the ADS5409 at 750 MHz and want to also clock the ADS54J20 at 750 MHz. They…
Hey Chuck,
Here is everything the sytems engineer could find on this device. We have not been able to get ahold of the design team for this chip. All of the sleep mode information i currently have on this device is seen below.
Part Number: ADS5409EVM Other Parts Discussed in Thread: LMX2572 Hello, I am using ADS5409EVM ADC Board and TSW1400EVM Capture Board. For the use of these boards, I need to generate a clock signal at 900MHz. However, it is said that the amplitude of this…
Part Number: ADS5409 Other Parts Discussed in Thread: ADS5400 , , ADS54J60 We have the following requirements in a Measurement system where we are considering usage of either ADS5409 or ADS5400:
1) 4mV – 1Vpk-pk differential input amplitude support (It…
Part Number: ADS5409 IN datasheet of ADS5409 on page 36 is description of 3A register.
We see that in D12-D11 default is 01 (LVDS SW - 2 mA to 2.75 mA). And in D15-D13 default is 110 (LVDS output current strength - 3.5 mA).
But we see note - in D12-D11 LVDS driver…
