The MAX3831/MAX3832 are 4:1 multiplexers (muxes) and 1:4 demultiplexers (demuxes) with automatic channel assignment.
The MAX3831/MAX3832 are 4:1 multiplexers (muxes) and 1:4 demultiplexers (demuxes) designed for SDH/SONET applications. Operating from a single +3.3V supply, these devices feature automatic channel assignment and include an on-chip PLL to synthesize high-frequency clocks for interfacing with optical or electrical drivers.
The MAX3831 provides a 622MHz LVDS clock output, while the MAX3832 provides a 155MHz LVDS clock output. Both devices support built-in self-test (BIST) via an embedded pattern generator and include system test flexibility through various loopback modes.
