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
(40°C to +85°C). The SY58027U is part of Micrel's Precision Edge® product family. All support documentation can be found on Micrel's web site at www.micrel.com.
