SY58626L

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
transmitter solutions, the output pre-emphasis duration
can be programmed from 60ps to 400ps.
The SY58626L operates at 3.3V ±10% supply and is
guaranteed over the commercial temperature range of
0°C to +70°C. The SY58626L transmitter is optimized to
work with the SY58627L receiver. The SY58626L is part
of Micrel's high-speed, Precision Edge® product line.
