LMK61E2 (ACTIVE)

Ultra-Low Jitter Fully Programmable Oscillator, Integrated EEPROM, +/-50ppm

 

Description

The LMK61E2 device is an ultra-low jitter PLLatinum programmable oscillator with a fractional-N frequency synthesizer with integrated VCO that generates commonly used reference clocks. The outputs can be configured as LVPECL, LVDS, or HCSL.

The device features self start-up from on-chip EEPROM that is factory programmed to generate 156.25-MHz LVPECL output. The device registers and EEPROM settings are fully programmable in-system through I2C serial interface. Internal power conditioning provide excellent power supply ripple rejection (PSRR), reducing the cost and complexity of the power delivery network. The device operates from a single 3.3-V ± 5% supply.

The device provides fine and coarse frequency margining options through I2C serial interface to support system design verification tests (DVT), such as standard compliance and system timing margin testing.
