M13X Device DS3/DS1 MUX/DEMUX, Enhanced Features TXC-03305 DATA SHEET FEATURES Multiplexes/demultiplexes 28 DS1 signals to/from a DS3 signal Integrated dejitter buffers to GR-499-CORE for all receive DS1 outputs, with bypass option M13 or C-bit parity format mode operation FEBE, C, or P-bit parity error insertion capability DS3 idle signal generators DS1 idle signal (QRS, AIS or ESF) generators DS3 LOS, LOF, P-bit parity, C-bit parity, AIS and idle detectors Integrated PMDL controller Receive or transmit DS1 LOS detectors DS2 LOF detectors External interface for receiving 14 C-bits and transmitting either 13 or 14 C-bits based on a control bit setting DS3 and DS2 X-bit access DS3 transmit and receive selectable AIS generation and detection Supports Intel, Motorola, or multiplexed microprocessor interfaces, and includes interrupt capability DS2 transmit/receive X-bit control/status 8 or 16-bit wide performance counters Reset lead Test Access Port for boundary scan Single +5V, ±5% power supply 208-lead Small Outline Plastic BGA package or 208-lead PQFP package (for M13E replacement) DESCRIPTION The M13X CMOS VLSI device provides the functions needed to multiplex and demultiplex 28 independent DS1 signals to and from a DS3 signal with either an M13 or C-bit frame format. It includes some enhanced features relative to the M13E device. A lead (M13X) is provided for selecting functional and software backwards compatibility with the M13E device (TXC-03303). Th...
