LMH0346SQE Description

Short technical summary and product information.

The Texas Instruments LMH0346SQE is a high-performance SDI reclocker supporting 3G, HD, and SD standards, including SMPTE 424M, SMPTE 292M, and SMPTE 259M(C). It operates with data rates up to 2.97 Gbps and supports DVB-ASI at 270 Mbps.

 

This device features a single 3.3V supply operation with a typical power consumption of 370 mW. It provides two differential, reclocked outputs, with an option for the second output to be a low-jitter, differential, data-rate clock output. The LMH0346SQE includes a single 27 MHz external crystal or reference clock input and manual or automatic rate select input. Additional features include an SD/HD operating rate indicator output, a lock detect indicator output, and an output mute function for data and clock.

 

The reclocker can operate in auto or manual bypass mode. It accepts differential LVPECL compatible serial data inputs and outputs, and LVCMOS control inputs and indicator outputs. The device is available in a 20-pin HTSSOP or a 24-pin WQFN package, both suitable for surface mounting. It operates within an industrial temperature range of -40°C to +85°C.

 

The LMH0346SQE is footprint compatible with the LMH0046 and LMH0026 in the HTSSOP package, making it a suitable option for upgrades or replacements in existing designs.
