LMH1219RTWT Description

Short technical summary and product information.

The LMH1219RTWT from Texas Instruments is a specialized integrated circuit designed for 12G SDI applications. This device functions as an adaptive cable equalizer with an integrated reclocker, supporting data rates up to 11.88 Gbps. It is compatible with various SDI standards including ST-2082-1 (12G), ST-2081-1 (6G), ST-424 (3G), ST-292 (HD), and ST-259 (SD), as well as SFF8431 (SFP+) for SMPTE 2022-5/6, DVB-ASI, and AES10 (MADI).

 

Key electrical features include a typical power consumption of 250 mW, with a power-saving mode down to 16 mW. The device offers configurable control via pins, SMBus, or SPI interfaces. It incorporates an adaptive cable equalizer at Input 0 and an adaptive board trace equalizer at Input 1, providing significant cable reach capabilities for different data rates.

 

Packaged in a 24-WQFN (4x5 mm) surface-mount form factor, the LMH1219RTWT operates within an industrial temperature range of -40°C to +85°C. Its design includes features like a 2:1 input mux, 1:2 fanout output with de-emphasis, and supports signal splitter mode. The IC powers from a single 2.5 V supply and includes an on-chip 1.8 V regulator.
