The SY58027U differential inputs include a unique internal termination design that allows access to the termination network through a VT pin. The device easily interfaces to different logic standards, both AC- and DCcoupled, without external resistor-bias and termination networks. The result is a clean, stub-free, low jitter interface solution. The differential 400mV LVPECL outputs have extremely fast rise/fall times guaranteed to be less than 80ps.
