In general, you get the lowest jitter by using a device with a lower propagation delay, i.e., with a higher maximum speed. The only 50 Mbps RS-4xx devices are 1+1 transceivers like the THVD1450.
LVDS allows higher data rates and is commonly used for clock…
Other Parts Discussed in Thread: SN65LVDS348 Hi,
we are using the sn65lvds348 quad receiver as an LVDS to LVTTL interface.
The EN control pin is pulled up to 4k7. All the output pins (LVTTL side) are pulled down to GND through 4K7 to ensure a known stat…
Hello Alec,
You could use a CML -> LVTTL -> LVDS . Please see the SN65LVDS348 or the SN65EPT23 both with a -40 Celsius operating temp.
Regards,
Gerardo
Other Parts Discussed in Thread: SN65LVDS348 , SN65LVDS352 , SN65LVDS33 My avionics customer is looking for a solution for translating from PECL Differential Standard to LVCMOS. At first glance through our parametric search I wasn't able to find anything…
Julian,
I agree higher input common mode range would help. Also lowering the common mode impedance would help.
Using a 50 ohm x 2 input termination for each LVDS Rx and adding a large common mode cap would damp the common mode coupling you are seeing…
