SY56216R Low Voltage 1.2V/1.8V/2.5V CML Dual Channel Buffer 4.5GHz/6.4Gbps with Equalization General Description Precision Edge The SY56216R is a fully-differential, low-voltage 1.2V/1.8V/2.5V CML Dual Channel Buffer with input Features equalization. The SY56216R can process clock signals as 1.2V/1.8V/2.5V CML Dual Channel Buffer fast as 4.5GHz or data patterns up to 6.4Gbps. Guaranteed AC performance over temperature and The differential input includes Micrels unique, 3-pin input voltage: termination architecture that interfaces to CML differential DC-to > 6.4Gbps Data throughput signals, without any level-shifting or termination resistor DC-to > 4.5GHz Clock throughput networks in the signal path. The differential input can also accept AC-coupled LVPECL and LVDS signals. Input <280ps propagation delay (IN-to-Q) voltages as small as 200mV (400mV ) are applied before pp <20ps within-device skew the 9, 18 or 27 FR4 transmission line. For AC-coupled <80ps rise/fall times input interface applications, an internal voltage reference High-speed CML outputs is provided to bias the V pin. The outputs are CML, with T 2.5V 5% V , 1.2/1.8V/2.5V 5% V power extremely fast rise/fall times guaranteed to be less than CC CCO supply operation 80ps. Industrial temperature range: 40C to +85C The SY56216R operates from a 2.5V 5% core supply and a 1.2V, 1.8V or 2.5V 5% output supply and is Available in 16-pin (3mm x 3mm) QFN package guaranteed over the full industrial temperature range Applications (40C to +85C). The SY56216R is part of Micrels high- speed, Precision Edge product line.
