SY58620L
Precision 4.25Gbps CML Backplane
Transceiver with Integrated Loopback
General Description
The SY58620L is a low jitter, high-speed transceiver
with a variable swing CML transmitter buffer and a CML
high-gain receiver optimized for precision telecom and
enterprise server transmission line and backplane data
management. The SY58620L distributes data to
4.25Gbps guaranteed over temperature and voltage.
The SY58620L transmitter differential input includes
Micrel鈥檚 unique, 3-pin input termination architecture that
directly interfaces to any (AC- or DC-coupled)
differential signal as small as 100mV (200mV
PP
) 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
(20mV
PP
). The outputs are 50鈩?source-terminated CML
with extremely fast rise/fall time.
To support remote self-testing, the SY58620L 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 SY58620L operates from a 3.3V 鹵10% supply and
is guaranteed over the full industrial temperature range
of 鈥?0擄C to +85擄C. The SY58620L is part of Micrel鈥檚
high-speed, Precision Edge
廬
product line.
