SY58052AU
Ultra-Precision CML Data and Clock
Synchronizer with Internal Input and Output
Termination
Precision Edge^®
General Description
The SY58052AU is an ultra-fast, precision, low jitter data-
to-clock resynchronizer with a guaranteed maximum data
throughput of 10.7Gbps and a maximum clock of 10.7GHz.
The SY58052AU 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 SY58052AU 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 50Ω environments
with internal 50Ω source termination and a 400mV output
swing.
The SY58052AU operates from a 2.5V or 3.3V supply and
is guaranteed over the full industrial temperature range
(−40°C to +85°C). The SY58052AU is part of a Micrel’s
Precision Edge^® product family.
