General Description

The SY55859L is a dual CML 2x2 crosspoint switch

optimized for high-speed data and/or clock applications

(up to 3.2Gbps or 2.7GHz) where low jitter and skew are

critical. This device is pin-for-pin, plug-in compatible to the

MAX3840. Each 2x2 of the SY55859L routes any input to

any output, and thus can distribute or multiplex a clock or

data stream. The I/O architecture is fully differential and

CML compatible. Both inputs and outputs are optimized for

are internally terminated with 50 , thus eliminating

external termination, and the outputs (QA0-1 and QB0-1)

include 50

saving output enable feature is provided which powers-

down unused outputs.

The SY5859L operates from a +3.3V ±10% supply, and is

guaranteed

temperature range.

5mm) QFN package.

For applications that require either lower voltage operation

or a more flexible input interface (for applications such as

AC–coupled LVPECL inputs), consider the SY55858U.
