DS90CR285: DS90CR285

Part Number: DS90CR285
Other Parts Discussed in Thread: SN65LVDS93A

Hi All,

I am using DS90CR285 transmitter component and I have sampling error (maybe noise), I have some questions about this component:

1. I didn't connect the unused pins to GND according to datasheet, what can happen at this condition? can a switcing noise trnsfer to other bits and change the logic state?

2. I didn't supplies the PLL voltage with isolated voltage, the PLL voltage connected with all the component voltage include FPGA, can it cause any sampling errors?

3. There is any new replacement component with more sampling window and low noise and jitter performance?

4. Can SN65LVDS93A replace this component?

thanks,
