SY58621L
Precision 3.2Gbps CML/LVPECL Backplane
Transceiver with Integrated Loopback
General Description
The SY58621L is a low jitter, high-speed transceiver
with a variable swing LVPECL transmitter buffer and a
CML high-gain receiver optimized for precision telecom
and enterprise server transmission line and backplane
data management. The SY58621L distributes data to
3.2Gbps guaranteed over temperature and voltage.
The SY58621L transmitter differential input includes
Micrel’s unique, patented 3-pin input termination
architecture that directly interfaces to any (AC- or DC-
coupled) differential signal as small as 100mV
(200mVPP) without any termination resistor network in
the signal path. The receiver differential input is
optimized to interface directly to AC-coupled signals as
small as 10mV (20mVPP). The receiver output is 50_
source-terminated CML and the transmitter output is
variable swing 80mV to 800mV LVPECL with extremely
fast rise/fall time.
To support remote self-testing, the SY58621L features a
high-speed loopback test mode. The input control signal
LOOPBACK enables an internal loopback path from the
transmitter input to the receiver output.
The SY58621L operates from a 3.3V ±10% supply and
is guaranteed over the full industrial temperature range
of –40°C to +85°C. The SY58621L is part of Micrel’s
high-speed, Precision Edge® product line. For
applications that requires a CML receiver and
transmitter, consider the SY58620L.
All support documentation can be found on Micrel’s web
site at: www.micrel.com.
