The LMK05028RGCR from Texas Instruments is a low-jitter, dual-channel network synchronizer clock designed for high-performance timing applications. It provides eight clock outputs supporting various formats including CML, HCSL, LVCMOS, LVDS, and LVPECL, with frequencies up to 750MHz.
This device features two independent PLL channels, offering 150fs RMS jitter for outputs at or above 100MHz and phase noise of -112dBc/Hz at 100Hz offset for 122.88MHz. It supports hitless switching with 50ps phase transient and phase cancellation, along with programmable loop bandwidth and Fastlock.
The LMK05028RGCR includes four reference clock inputs and supports priority-based input selection. It offers digital holdover on loss of reference and can translate any input frequency to any output frequency. The device is configurable via I2C or SPI interfaces and includes EEPROM/ROM for custom clocks on power-up.
Packaged in a 64-VQFN (9x9 mm) with a surface mount type, this clock synchronizer operates within an industrial temperature range of -40°C to 85°C. It is suitable for applications requiring precise timing synchronization and low jitter.
