The MAX3992UTG+ is a 10Gbps clock and data recovery (CDR) IC with an integrated equalizer, designed for XFP optical transmitters. It operates at data rates from 9.95Gbps to 11.1Gbps and supports SONET OC-192/SDH STM-64, Ethernet, and Fibre-Channel applications. The device recovers data across up to 12 inches of FR-4 and one connector without external equalization. It features CML inputs and outputs, a single +3.3V supply (3.0V to 3.6V), and consumes 356mW. Operating temperatures range from 0°C to +85°C in a 24-pin QFN package.
Verify the component status as discontinued or limited availability through official Analog Devices channels. Confirm RoHS compliance (+ suffix indicates lead-free). Ensure the exposed pad is properly soldered to ground for thermal performance. Check for valid datasheet revisions before integration.
Select this part for XFP modules requiring signal conditioning over short copper traces. Ensure the reference clock frequency matches Rb/16 or Rb/64 within ±100ppm. Use a 0.047µF capacitor between CFIL and VCC for PLL dampening. Verify CML termination requirements for SDI± and SDO± interfaces.
The MAX3992 forms a chipset with the MAX3991 (CDR with limiting amplifier) for XFP transceiver modules. It is part of the Maxim Integrated product line, now under Analog Devices. The device is specifically optimized for jitter tolerance in SONET, Ethernet, and Fibre-Channel environments.
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices for current alternatives if the MAX3992UTG+ is unavailable.
