The MAX3831/MAX3832 are 4:1 multiplexers (muxes) and 1:4 demultiplexers (demuxes) with automatic channel alignment. 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 high-frequency 2.488GHz clock for timing the outgoing data streams.\n 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 provides a 155MHz LVDS clock output. An internal frame detector looks for a 622Mbps SDH/SONET framing pattern and rolls the demux to maintain proper channel assignment at the outputs.\n These devices also include an embedded pattern generator that enables a full-speed, built-in self-test (BIST). Two different loopback modes provide system test flexibility. 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.

高精度、低电压、SPST、CMOS模拟开关; \n• Single-Supply Operation (+3V to +15V) \n• Bipolar-Supply Operation (±3V to ±8V) \n• Pin-Compatible with DG401/DG403/DG405 \n• Low On-Resistance, 20Ω Typical (35Ω Max) \n• Guaranteed Matched On-Resistance Between Channels, < 2Ω \n• Guaranteed Flat On-Resistance over Specified Analog Signal Range, < 4Ω \n• Guaranteed Charge Injection, < 5pC \n• Guaranteed Off-Channel Leakage, < 2.5nA at +85°C \n• TTL/CMOS-Logic Compatible with 3V, 5V, ±3V, and ±5V Supplies \n• Rail-to-Rail Analog Signal Handling Capability;

The MAX381/MAX383/MAX385 are precision, low-voltage analog switches. The single-pole single-throw MAX381 and double-pole single-throw MAX385 dual switches are normally open. The single-pole double-throw MAX383 has two normally open and two normally closed poles. All three parts offer low on-resistance (less than 35Ω), guaranteed to match to within 2Ω between channels and to remain flat over the specified analog signal range (4Ω max). They also offer low leakage (less than 250pA at +25°C and less than 2.5nA at +85°C) and fast switching (turn-on time less than 175ns and turn-off time less than 100ns).\n The MAX381/MAX383/MAX385 are fabricated with Maxim's low-voltage silicon-gate process for high system accuracy. Design improvements guarantee extremely low charge injection (< 5pC) and low power consumption (< 10µW).\n These monolithic switches operate with a single positive supply (+3V to +15V) or with split supplies (±3V to ±8V) while retaining CMOS-logic input compatibility and fast switching. CMOS inputs provide reduced input loading.
