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 u nique, p atented 3 -pin i nput t ermination architecture that directly interfaces to any (AC- or DCcoupled) d ifferential s ignal a s s mall a s 1 00mV (200mVPP) without any termination resistor network in the s ignal p ath. T he r eceiver d ifferential i nput i s 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.
