Hi,
one of my Customers is using the SN65LVDS179-EP in the below configuration as transmitter only:
The transceivers are used to transmit the system clocks for boards NUM1 and NUM2 and therefore they need that the differential 40MHZ sent are as synchronized as possible.
The questions are:
1. Propagation delay: the datasheet specifies a maxim of 4.5ns over the full temperature range and 1.7ns typ. Is this propagation delay always constant for a certain temperature for a given part or could it vary and generate some jitter between the two LVDS clocks?
2. Jitter generation: Is the transceiver susceptible to add jitter to the input signal or will the LVDS clock signal have the same jitter/same output precession at the output as in the input?
3. Can you think about anything else that may cause some jitter or delay between both clocks?
Thanks, Beatriz.
