Normally it is not a good idea to use the FPGA as a clock source for the ADC. These clocks usually have poor phase noise which directly effects the performance of the ADC. See attached…
User,
SYSREF has nothing to do with jitter. This is only used to synchronize multiple devices. The input clock divider allows more flexibility for system clock architecture design. This will not help with jitter.
SYSREF only works if CLK DIV is set…

Please see the attached document regarding your jitter question. Basically, the less jitter, the better the performance. This document will show you how to calculate the ADC performance…
Mahmoud,
Most of our newer high speed ADC use clock device from the LMK family, such as the LM04828. You will need to figure out how much SNR performance you need out of the ADC. From this, you can figure out the jitter requirements of the clock source…
Hi,
The ADS5483 does not have any registers addressable by SPI to configure the device itself, so everything for the ADS5483 EVM is configurable by jumper or solder option with no PC interaction needed. The TSW1200 Capture Card does have a register…
Other Parts Discussed in Thread: ADC16DV160 , ADS5483 Hello Guys
We are designing an ADC FMC card with 4 channels. We intend to prototype two boards, with two different converters, one running at maximum 130 MSPS and other with maximum 250 MSPS, both…
Good morning...
to your question / answer #2:
the data is not realy multiplexed - it' is in a dual data rate format. .. As you can see below there is the timing information of the ADS5483 and ADS62P49 (both use ddr as output) .
The difference…

Henry,
The schematic appears to be fine. What is sourcing the clock? SNR is directly related to the phase noise of the clock. If you want better SNR, provide a cleaner clock.

Jim

Other Parts Discussed in Thread: TUSB3410 , ADS5485 , ADS6445 , ADS5483 Hi,
My name is Chang Shin.
I'm thinking of using ADC5485 to record my fluorescence signal.
So I ordered ADS5485EVM, TSW1200EVM, hoping to develop the necessary program. …
