SY55859LMG Microchip

SY55859L 3.3V, 3.2Gbps Dual 2X2 Crosspoint Switch General Description TM The SY55859L is a dual CML 2x2 crosspoint switch SuperLite optimized for high-speed data and/or clock applications Features (up to 3.2Gbps or 2.7GHz) where low jitter and skew are critical. This device is pin-for-pin, plug-in compatible to the Pin-for-pin, plug-in compatible to the MAX3840 MAX3840. Each 2x2 of the SY55859L routes any input to Supply voltage operation: +3.3V10% any output, and thus can distribute or multiplex a clock or Low Jitter: data stream. The I/O architecture is fully differential and -2ps random jitter RMS CML compatible. Both inputs and outputs are optimized for -5ps deterministic jitter PP 50 transmission lines. The inputs (DA 0-1 and DB 0-1) Power saving output disable feature are internally terminated with 50 , thus eliminating 15ps channel-to-channel skew external termination, and the outputs (QA0-1 and QB0-1) include 50 source termination. Furthermore, a power- Fast CML outputs: <100ps t /t r f saving output enable feature is provided which powers- Available in a small (5mm x 5mm) 32-pin EPAD-QFN down unused outputs. package The SY5859L operates from a +3.3V 10% supply, and is guaranteed over the industrial (40C to +85C) Applications temperature range. It is available in a 32-pin (5mm x 5mm) QFN package. SONET/SDH optical transport For applications that require either lower voltage operation High-speed backplane redundancy or a more flexible input interface (for applications such as Add-drop multiplexers ACcoupled LVPECL inputs), consider the SY55858U.
