Single-chip multiplexer
Single-chip multiplexer
The E123 mux multiplexes 16 E1 (2.048-Mbit/sec) signals onto a single E3 (34.368-Mbit/sec) line. This single-chip device provides full bidirectional access to all four of the intermediate E2 (8.448-Mbit/sec) stages. The chip integrates extensive diagnostics, including a built-in pseudo-random binary sequence generator. Packaged in a 208-pin plastic quad flat pack, E123 mux has full jtag-compliant boundary scan. Operating temperature is -40 to +85C.
