SY89543L

Micrel, Inc. 3.3V, 3.2Gbps DUAL, DIFFERENTIAL 2:1 LVDS MULTIPLEXER with INTERNAL TERMINATION Precision Edge® Precision ESdYg89e5®43L SY89543L FEATURES Dual 2:1 multiplexer Guaranteed AC performance over temp and voltage: DC-to > 3.2Gbps data rate throughput < 510ps In-to-Out tpd < 150ps tr/tf Ultra-low jitter design: < 1psRMS random jitter < 10psPP deterministic jitter < 10psPP total jitter (clock) < 0.7psRMS crosstalk-induced jitter Unique input isolation design minimizes crosstalk Internal input termination Unique input termination and VT pin accepts DCcoupled and AC-coupled inputs (LVDS, LVPECL, CML) 350mV LVDS output swing CMOS/TTL compatible MUX select Power supply 3.3V +10% –40 to +85°C temperature range Available in 32-pin (5mm x 5mm) MLF® package APPLICATIONS Precision Edge® DESCRIPTION The SY89543L includes two precision, high-speed 2:1 differential Muxes with LVDS (350mV) compatible outputs with a guaranteed data rate throughput of 3.2Gbps over temperature and voltage. The SY89543L differential inputs include a unique, 3-pin internal termination that allows access to the termination network through a VT pin. This feature allows the device to easily interface to different logic standards, both AC- and DC-coupled without external resistor-bias and termination networks. The result is a clean, stub-free, low jitter interface solution. The SY89543L operates from a single 3.3V supply, and is guaranteed over the full industrial temperature range (–40°C t...
