The SY58052U is an ultra-fast, precision, low jitter data-
to-clock resynchronizer with a guaranteed maximum data
and clock throughput of 10.7Gbps or 7GHz, respectively.
The SY58052U is an ideal solution for backplane retiming
or retiming after the data passes through long trace lengths.
Serial data comes into the data input, and the CML output
is synchronous to the input reference clock’s rising edge.
The SY58052U differential inputs include a unique,
internal termination design that allows access to the
termination network through a V
T
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 differential CML output is
optimized for 50
environments with internal 50
source
termination and a 400mV output swing.
The SY58052U operates from a 2.5V or 3.3V supply and
is guaranteed over the full industrial temperature range
(–40
°
C to +85
°
C). The SY58052U is part of a Micrel’s
Precision Edge
product family.
