19-1534; Rev 1; 10/99 MAX3831/MAX3832 +3.3V, 2.5Gbps, SDH/SONET, 4-Channel Interconnect Mux/Demux ICs with Clock Generator General Description The MAX3831/MAX3832 are 4:1 multiplexers (muxes) and 1:4 demultiplexers (demuxes) with automatic channel assignment. Operating from a single +3.3V supply, the mux receives four parallel, 622Mbps SDH/SONET channels. These channels are bit interleaved to generate a serial data stream of 2.488Gbps for interfacing to an optical or an electrical driver. A 10-bit-wide elastic buffer tolerates up to ±7.5ns skew between any parallel data input and the reference clock. An external 155MHz reference clock is required for the on-chip PLL to synthesize a...
