General Description
The MAX3831/MAX3832 are 4:1 multiplexers (muxes)
and 1:4 demultiplexers (demuxes) with automatic chan-
nel assignment. Operating from a single +3.3V supply,
the mux receives four parallel, 622Mbps SDH/SONET
channels. These channels are bit interleaved to gener-
ate 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 high-frequency 2.488GHz clock for tim-
ing the outgoing data streams.
The MAX3831/MAX3832’s demux receives 2.488Gbps
serial data and the 2.488GHz clock from an external
clock/data recovery device (MAX3876), converting it to
four 622Mbps LVDS outputs. The MAX3831 provides a
622MHz LVDS clock output, and the MAX3832 pro-
vides a 155MHz LVDS clock output. An internal frame
detector looks for a 622Mbps SDH/SONET framing pat-
tern and rolls the demux to maintain proper channel
assignment at the outputs.
These devices also include an embedded pattern gen-
erator that enables a full-speed, built-in self-test (BIST).
Two different loopback modes provide system test flexi-
bility. A TTL loss-of-frame monitor is included. The
MAX3831/MAX3832 are available in 64-pin TQFP-EP
(exposed paddle) packages and are specified over the
upper commercial (0°C to +85°C) temperature range.
