XRT59L91 Datasheet (Exar Corporation) - Single-Chip E1 Line Interface Unit

XRT59L91, Single-Chip E1 Line Interface Unit

The XRT59L91 is an optimized single-chip analog 3.3V E1 line interface unit (LIU) fabricated using low power CMOS technology.

The LIU IC consists of both a Transmitter and a Receiver function.

The Transmitter accepts a TTL or CMOS level signal from the Terminal Equipment; and outputs this data to th
