Design & Manufacture
Mouser now stocks the Texas Instruments LMK61E2 ultra low-jitter
fully-programmable PLLatinum oscillator with a fractional-N frequency
synthesizer.
The device includes 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 I2C serial interface.
Internal power conditioning provides exceptional 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
I2C serial interface to support system design verification tests (DVT), such
as standard compliance and system timing margin testing.
