SY58626L
DC-to-6.4Gbps Backplane Transmit Buffer with
Selectable Output Pre-emphasis, I/O DC-Offset
Control, and 200mV-3.0VPP Output Swing General Description
The SY58626L high-speed, low jitter transmit buffer is
optimized for backplane and transmission line data-path
management applications in Automatic Test Equipment
(ATE) and Test & Measurement (T&M) systems. The
buffer includes a CML compatible, variable swing output
with selectable pre-emphasis.
The SY58626L is
capable of driving serial data from DC through 6.4Gbps
with a 3VPP (1.5VPK single ended) differential swing.
The SY58626L differential input includes Micrel’s
unique, 3-pin input termination architecture that directly
interfaces to any DC-or AC-coupled, differential signal
as small as 100mVPK without any termination resistor
networks in the signal path. The outputs are 50Ω
source-terminated CML with a programmable output
swing from 200mVPP to 3VPP (100mVPK to 1.5VPK).
The SY58626L includes an output stage that provides 4
levels of pre-emphasis. The output pre-emphasis level is
programmed with a three-bit interface. Unlike other …
