SY58621L Datasheet | Micrel Semiconductor

.. 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 tele 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 DCcoupled) differential signal as small as 100m V (200m VPP) 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 10m V (20m VPP). The receiver output is 50_ source-terminated CML and the transmitter output is variable swing 80m V to 800m V 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.
