General Description

The SY562

16R 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 (400mV

pp

) 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 V

T

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.
