3 Description
The LMK61XX is an ultra-low jitter oscillator that
generates a commonly used reference clock. The
device is pre-programmed in factory to support any
reference clock frequency; supported output formats
are LVPECL up to 1 GHz, LVDS up to 900 MHz, and
HCSL up to 400 MHz. 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.
