The LMH1983SQE/NOPB from Texas Instruments is a programmable audio/video (A/V) clock generator designed for broadcast and professional applications. It integrates multiple PLLs and VCXOs, enabling support for SMPTE serial digital video (SDI) and digital audio AES3/EBU standards.
This device offers low-jitter reference clocks crucial for SDI transmitters to meet stringent output jitter specifications. Key features include four PLLs for simultaneous A/V clock generation, a 3x2 video clock crosspoint, and flexible PLL bandwidth for optimizing jitter performance and lock time. It operates on a single 3.3V supply and features an I2C interface with an address select pin.
The LMH1983SQE/NOPB is housed in a 40-WQFN (6x6) package and supports surface mount. It operates within a temperature range of -40°C to 85°C. The device includes status flags for loss of reference and PLL lock, and supports digital holdover or free-run on loss of reference.
This clock generator is suitable for applications requiring precise clock generation for professional video and audio synchronization.
