General Description
The SY56216R is a fully-differential, low-voltage
1.2V/1.8V/2.5V CML Dual Channel Buffer with input
equalization. The SY56216R can process clock signals as
fast as 4.5GHz or data patterns up to 6.4Gbps.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that interfaces to CML differential
signals, without any level-shifting or termination resistor
networks in the signal path. The differential input can also
accept AC-coupled LVPECL and LVDS signals. Input
voltages as small as 200mV (400mVpp) are applied before
the 9”, 18” or 27” FR4 transmission line. For AC-coupled
input interface applications, an internal voltage reference
is provided to bias the VT pin. The outputs are CML, with
extremely fast rise/fall times guaranteed to be less than
80ps.
The SY56216R operates from a 2.5V ±5% core supply
and a 1.2V, 1.8V or 2.5V ±5% output supply and is
guaranteed over the full industrial temperature range
(–40°C to +85°C). The SY56216R is part of Micrel’s high-
speed, Precision Edge® product line.
