DESCRIPTION
a73 Guaranteed f
MAX
>2.5GHz over temperature
a73 2.3V to 5.7V power supply
a73 Non-blocking “switch architecture”
a73 Guaranteed <15ps channel-to-channel skew
a73 Guaranteed <480ps propagation delay over
temperature
a73 Configurable as 2:1 mux, 1:2 fan-out buffer, dual
buffer, or 2 x 2 switch
a73 Accepts CML, PECL, LVPECL inputs
a73 Fully differential inputs/outputs
a73 Source terminated CML outputs for fast edge rates
a73 Wide operating temperature range: –40°C to +85°C
a73 Available in a tiny 16-pin EPAD-QSOP package
The SY55854U is a fully differential, CML, 2 x 2-
crosspoint switch. The non-blocking design allows any
input to be connected to any output. Varying the state of
the select inputs allows SY55854U to be used in backup,
fault tolerant, protection, and backplane distribution
applications.
SY55854U inputs can be terminated with a single
resistor between the true and the complement pins of a
given input.
The SY55854U is a member of Micrel’s new
SuperLite? family of high-speed logic devices. This family
features very small packaging, high signal integrity, and
flexible supply voltage operation.
