DESCRIPTION
The SY58027U features two ultra-fast, low jitter 2:1
differential muxes with a guaranteed maximum data
throughput of 10.7Gbps.
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 DC-
coupled, 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.
The SY58027U operates from a 2.5V or 3.3V supply and
is guaranteed over the full industrial temperature range
(â40°C to +85°C). The SY58027U is part of Micrelâs Precision
Edge® product family.
