What are the key features of LMH0344GR?
- Adaptive cable equalization for SD-SDI, HD-SDI, and 3G-SDI standards at data rates up to 2.97 Gbps
- 25-ball Fine-Pitch BGA (5×5 mm) package enables dense video-processing PCB layouts
- Single-function design simplifies integration into broadcast and professional video signal chains
- Pb-free, RoHS-compliant construction meets modern environmental regulations for global distribution
What is LMH0344GR used for?
The LMH0344GR is designed for professional broadcast and video distribution equipment requiring equalization of coaxial cable losses in SD-SDI (270 Mbps), HD-SDI (1.485 Gbps), and 3G-SDI (2.97 Gbps) signal paths. It is used in production switchers, routing systems, and video routers to restore signal integrity after cable runs of 100 m or more. The compact 25-ball Fine-Pitch BGA package suits multi-channel video cards where PCB area is tightly constrained.

Frequently Asked Questions
What video data rates does the LMH0344GR equalize and over what cable lengths?
The LMH0344GR supports adaptive equalization for SD-SDI at 270 Mbps, HD-SDI at 1.485 Gbps, and 3G-SDI at 2.97 Gbps. It compensates for the frequency-dependent losses of standard 75-ohm coaxial cable, typically restoring signal integrity after cable runs extending up to approximately 100 m at 3G-SDI rates and longer distances at SD-SDI rates.
How does the LMH0344GR Fine-Pitch BGA package compare to SOIC packages for multi-channel video card designs?
The LMH0344GR uses a 25-ball Fine-Pitch BGA measuring 5×5 mm with 1.0 mm ball pitch, occupying roughly 25 mm² of board area. A comparable SOIC-16 package would require approximately 60 mm² including pad courtyard. For a 16-channel SDI input card, the BGA option saves over 500 mm² of PCB space, enabling higher channel density in the same card slot form factor.
Is the LMH0344GR a suitable drop-in alternative to the LMH0341 for existing HD-SDI equalizer designs?
The LMH0344GR and LMH0341 share similar adaptive equalization functions for HD-SDI at 1.485 Gbps, but the LMH0344GR adds 3G-SDI support at 2.97 Gbps and uses a smaller 25-ball BGA versus the LMH0341's larger footprint. Designers migrating from LMH0341 must verify that their PCB land pattern accommodates the fine-pitch BGA footprint and that their power supply meets the LMH0344GR's supply requirements.
What supply voltage does the LMH0344GR require for broadcast equipment integration?
The LMH0344GR is designed for 3.3 V supply operation, which is the standard low-voltage rail available on most broadcast PCBs and FPGA-based video processing cards. This 3.3 V supply compatibility simplifies integration alongside modern FPGAs and serializer/deserializer devices without requiring additional voltage regulators on the board.
