The LMK61E08 is an ultra-low jitter programmable oscillator from Texas Instruments, designed for high-performance applications. It utilizes fractional-N frequency synthesizers with integrated VCOs to generate reference clocks, configurable as LVPECL, LVDS, or HCSL outputs. The device features a self-start-up capability from on-chip EEPROM, allowing for factory-programmed default output frequencies or fully programmable settings via an I¬=C interface. It supports fine and coarse frequency margining control, enabling adjustments without output spikes or glitches, which is beneficial for system design verification tests. The oscillator operates at a voltage of 3.3 V and is rated for an industrial temperature range of -40¬?C to +85¬?C. With a typical jitter of 90 fs RMS for output frequencies above 100 MHz and a total frequency tolerance of ¬±25 ppm, the LMK61E08 is suitable for applications in networking, medical imaging, and broadcast video. The package dimensions are 7 mm x 5 mm in a 6-pin configuration.
