www.DataSheet4U.com STLVD112 HIGH SPEED PROTECTION SWITCH s s s s s 24mA CMOS OUTPUT DRIVE CURRENT LVTTL INPUT THRESHOLDS CONTROLLED SKEW BETWEEN DATA AND CLOCK SIGNALS LVDS INPUT-OUTPUT UP TO 155 MHZ IMPROVED LATCH-UP IMMUNITY UP TO 300mA DESCRIPTION The STLVD112 is a low voltage differential to LVTTL signal converter with enhanced loop-back and crosspoint features. The synchronous design allows a phase alignment between a clock and its data; this means a better BER (Bit Error Rate) performance. The advanced 0.35µm technology makes the STLVD112 suitable for data rates up to 200Mbit. The main application field is SDH/SONET telecom infrastructure. The STLVD112 flexible switch architecture makes it easy to implement multiple protection schemes in STM1 access systems. Thanks to the flexible multiplexing allowed, it becomes simple to redirect the data/clock signal coming from the faulty access card to the spare card. In normal mode the STLVD112 converts the differential data levels of the LVDS and related ORDERING CODES Type STLVD112BTR STLVD112CTR Temperature Range -40 to 85 °C 0 to 70 °C Package TSSOP clock signal from (to) the line interface in LVTTL level signals to (from) the backpanel. In addition the switch functions prevent the equipment from line interface faults. In fact, it is possible to switch the signals coming from a different line interface to the local line interface or the signals from the local line interface to a different line interface.
