LMH0346MHX

Video Processing Overview

The LMH0346MHX/NOPB is a high-speed clock recovery integrated circuit designed for serial digital interface (SDI) video applications. It functions as an HD/SD SDI reclocker, supporting data rates up to 3 Gbps. The device accepts single-ended or differential input signals and provides dual differential outputs. It integrates a phase-locked loop (PLL) with a voltage-controlled oscillator (VCO) to recover the clock signal from the incoming video data stream. The component is housed in a 20-pin HTSSOP package.

Video Processing Feature Summary

• Supports both High Definition (HD) and Standard Definition (SD) serial digital interface standards
• Integrates a high-performance PLL for precise clock recovery from serial data streams
• Provides dual differential output drivers for flexible system interfacing

Video Processing Applications

• Professional video distribution systems requiring signal regeneration
• Broadcast equipment utilizing HD/SD SDI formats
• Video monitoring and routing infrastructure

Video Processing Procurement Notes

Verify the specific ordering suffix, such as /NOPB, against the manufacturer's current datasheet to confirm lead-free compliance and exact package variant. Confirm availability status as components may be subject to obsolescence notices. Ensure the selected package matches the target PCB footprint requirements before finalizing procurement orders.

Video Processing Selection Notes

Select this component when designing circuits that require robust clock recovery for serial video signals up to 3 Gbps. Consider the HTSSOP package constraints for thermal management and board space. Evaluate the need for dual differential outputs versus single-ended interfaces to determine if additional buffering is required in the signal chain.
