MAX3992

10Gbps Clock and Data Recovery with Equalizer


Please check latest availability status for a specific part variant.

Description

The MAX3992 is a 10Gbps clock and data recovery (CDR) with equalizer IC for XFP optical transmitters. The MAX3992 and the MAX3991 (CDR with limiting amplifier) form a signal conditioner chipset for use in XFP transceiver modules. The chipset is XFI compliant and offers multirate operation for data rates from 9.95Gbps to 11.1Gbps.

The MAX3992 recovers the data for up to 12 inches of FR-4 and one connector without the need for a standalone equalizer. The phase-locked loop is optimized for jitter tolerance in SONET, Ethernet, and Fibre-Channel applications. Low jitter generation of 4mUIRMS leaves adequate margin for meeting SONET jitter requirements at the optical output.

An AC-based power detector asserts the loss-of-signal (LOS) output when the input signal is removed. An external reference clock, with frequency equal to 1/64 or 1/16 of the serial data rate, is used to aid in frequency acquisition. A loss-of-lock (LOL) indicator is provided to indicate the lock status of the receiver PLL.

The MAX3992 is available in a 4mm x 4mm, 24-pin QFN package. It consumes 356mW from a single +3.3V supply and operates over a 0°C to +85°C temperature range.
