The LMH0344GR is a high-performance, low-power single-channel SDI serializer designed by Texas Instruments to support video interfaces for SD-SDI, HD-SDI, and 3G-SDI data rates. This versatile chip is well-suited for a range of professional video and broadcast applications, including cameras, switchers, routers, and monitors.
The device converts 20-bit parallel data to a serial data stream. This stream can be output on either a single differential source-terminated pair or a dual differential source-terminated pair for reduced electromagnetic interference (EMI). The LMH0344GR supports SMPTE 259M, SMPTE 292M, SMPTE 424M, and DVB-ASI standards, making it a highly compatible solution for a variety of digital video formats.
With its integrated cable driver, the LMH0344GR is capable of driving 75Ω transmission lines (coaxial cables) up to 120m at 2.97 Gbps. This ensures reliable long-distance communication, which is essential for professional video production environments. The device also features an adaptive cable equalizer, which compensates for transmission medium losses and optimizes performance over a variety of physical mediums.
Energy efficiency is a key aspect of the LMH0344GR, with a typical power consumption of only 160 mW. This makes it an ideal choice for applications where power efficiency is critical, such as portable and battery-operated equipment. Additionally, the serializer is available in a compact 48-pin WQFN package, which is conducive to space-constrained designs.
Other notable features of the LMH0344GR include an integrated reclocker, which reduces jitter and improves signal integrity, and programmable outputs that allow for control over signal parameters such as swing and de-emphasis. This level of customization ensures that the device can be fine-tuned to meet the specific requirements of the application at hand.
For developers and engineers looking to incorporate the LMH0344GR into their designs, Texas Instruments provides comprehensive technical support, including datasheets, reference designs, and simulation tools to facilitate the integration process.
