SY89542U

Micrel, Inc. 2.5V, 3.2Gbps DUAL, DIFFERENTIAL 2:1 LVDS MULTIPLEXER WITH INTERNAL TERMINATION Precision Edge® Precision ESdY8g9e5®42U SY89542U FEATURES ■ Dual 2:1 multiplexer ■ Guaranteed AC performance over temp and voltage: DC-to > 3.2Gbps data rate throughput < 600ps 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 DC-Coupled and AC-coupled inputs (LVDS, LVPECL, CML) ■ 350mV LVDS output swing ■ CMOS/TTL compatible MUX select ■ Power supply 2.5V ±5% ■ –40°C to +85°C temperature range ■ Available in 32-pin (5mm x 5mm) MLF® package APPLICATIONS DESCRIPTION Precision Edge® The SY89542U 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 SY89542U 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 SY89542U operates from a single 2.5V supply, and is guaranteed over the full industrial ...
