LTC1520CS#PBF

LTC1520CS#PBF is a high speed, precision differential line receiver that can operate at data rates as high as 50Mbps. A unique architecture provides very stable propagation delays and low skew over a wide input common mode, input overdrive and ambient temperature range. Propagation delay is 18ns ±3ns, while typically tPLH/tPHL skew is 500ps and channel-to-channel skew is 400ps. Each receiver translates differential input levels into valid CMOS and TTL output levels. Its high input resistance allows many receivers to be connected to the same driver. The receiver outputs go into a high impedance state when disabled. Protection features include thermal shutdown and a controlled maximum short-circuit current that does not oscillate in and out of short-circuit mode. Application includes high speed backplane interface, line collision detector, PECL and LVDS line receivers, level translator, ring oscillator, tapped delay line.
