Hi team,

My customer is looking for 12channel clk buffer, the input is 3.3v TTL 25Mhz, the output is LVDS or HCSL. The line length is 50cm. Do you have some suggestions? Thanks.

CDCLVD1212 is the best recommendation, however this device has VCC = 2.5V, therefore you would need to attenuate the input. You could simulate the transmission line of your desired length using the IBIS model.

Kind regards,
Lane
