Seven frequencies, three output standards, one BOM line
The LMK61PD0A2-SIAR is a standard crystal oscillator (XO) from Texas Instruments that replaces up to seven discrete fixed-frequency oscillators with a single 8-SMD part. It ships with one of seven factory-programmed output frequencies — 62.5MHz, 100MHz, 106.5MHz, 125MHz, 156.25MHz, 212.5MHz, or 312.5MHz — and can be ordered for any of those rates without a separate programming step. The output driver is configurable to HCSL, LVDS, or LVPECL, so the same oscillator can feed a PCIe reference clock, a SerDes PLL, or a gigabit Ethernet PHY without a level translator. That cuts qualification time and inventory lines. Supply voltage tolerance is 3.135V to 3.465V (3.3V nominal ±5%), which keeps the oscillator locked through the typical 50 mV ripple on a switching regulator rail.
The 8-SMD module measures 7.00 mm x 5.00 mm with a seated height of 1.15 mm — a standard footprint that drops onto existing 8-pin oscillator pads without a layout change.
Active production, no obsolescence watch needed
Confirm the exact frequency variant when ordering — the factory programs the output at manufacture, and the part cannot be field-reconfigured.
