• DC-to > 3.2Gbps data rate throughput

DESCRIPTION

• < 600ps In-to-Out t

• < 150ps t /t

r f

The SY89542U includes two precision, high-speed 2:1

differential Muxes with LVDS (350mV) compatible outputs

with a guaranteed data rate throughput of 3.2Gbps over

temperature and voltage.

• < 1ps

random jitter

• < 10ps deterministic jitter

• < 10ps total jitter (clock)

The SY89542U differential inputs include a unique, 3-pin

internal termination that allows access to the termination

• < 0.7ps

network through a V pin. This feature allows the device to

easily interface 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 SY89542U operates from a single 2.5V supply, and

is guaranteed over the full industrial temperature range

(–40°C to +85°C). For applications that require a 3.3V supply,

consider the SY89543L. The SY89542U is part of Micrel’s

Precision Edge product family.
