LMK6HA15625ADLER

LMK6HA15625ADLER is a Texas Instruments fixed-frequency 156.25 MHz HCSL oscillator built on TI's BAW resonator technology, in the 3.2 by 2.5 mm 6-pin VSON (DLE) package, decoded per the LMK6 ordering scheme in TI document SNAA415. The 156.25 MHz output with 100 fs typical (125 fs maximum) RMS jitter at that frequency is the standard reference for Ethernet and PCIe clock trees, and TI rates the device compliant with PCIe Generations 1 through 7, so one reference covers current and next-generation root-complex designs. It operates from a 2.5 V to 3.3 V supply, holds plus/minus 25 ppm total stability including 10-year aging, rejects supply noise at -72 dBc with 500 kHz ripple and starts in under 5 ms; temperature range is -40 to +85 degrees C. Selection advice: read the function pin before ordering — on this code pin 1 is a Standby function, not output enable, and firmware or board control must be planned accordingly; the marking on the device is LHA2. As with all LMK6 codes, frequency, format, function, supply and package are fixed at the factory, so the full orderable code must be stated exactly in the RFQ. Parameters verified against TI documentation.
