Linear Technology
DESCRIPTION
The LTC®1520 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.
