Part Details:

STLVD112 High speed protection switch Features 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 TSSOP 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. card. In normal mode the STLVD112 converts the differential data levels of the LVDS and related The advanced 0.35ìm technology makes the clock signal from (to) the line interface in LVTTL STLVD112 suitable for data rates up to 200Mbit. level signals to (from) the backpanel. In addition The main application field is SDH/SONET the switch functions prevent the equipment from telecom infrastructure. The STLVD112 flexible line interface faults. In fact, it is possible to switch switch architecture makes it easy to implement the signals coming from a different line interface multiple protection schemes in STM1 access to the local line interface or the signals from the systems. local line interface to a different line interface. Thanks to the flexible multiplexing allowed, it becomes simple to redirect the data/clock signal coming from the faulty access card to the spare Order codes Temperature Part number Package Packaging range STLVD112BTR -40 to 85 °C TSSOP48 (Tape & Reel) 1000 parts per reel May 2007 Rev. 3 1/15 www.st.com 15 STLVD112 Contents 1 Pin configuration . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 2 Truth tables . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 3 Maximum ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 4 Electrical characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 5
