LMK61E2 Ultra-Low Jitter Programmable Oscillator

Texas Instruments LMK61E2 Ultra-Low Jitter Fully Programmable Oscillator is a PLLatinum™ programmable oscillator with a fractional-N frequency synthesizer. These include an integrated VCO that generates commonly used reference clocks. The outputs can be configured as LVPECL or LVDS or HCSL. The device features self-startup from on-chip EEPROM that is factory programmed to generate 156.25MHz LVPECL output. The device registers and EEPROM settings are fully programmable in-system via the I²C serial interface. Internal power conditioning provides excellent power supply ripple rejection (PSRR), reducing the cost and complexity of the power delivery network. The device provides fine and coarse frequency margining options via the I²C serial interface to support system design verification tests (DVT), such as standard compliance and system timing margin testing.
