Seven frequencies, three output standards — one footprint
This is a standard crystal-based XO that can be ordered or configured for any of seven output frequencies: 62.5, 100, 106.5, 125, 156.25, 212.5, or 312.5 MHz. The output driver supports HCSL, LVDS, or LVPECL — no external level-shifting resistors needed. That means a single 8-SMD module can serve as the reference for a 1000BASE-T PHY, a PCIe Gen3 clock, or a SerDes frame buffer, depending on the frequency and output type selected at order.
Wide supply and temperature envelope
Supply range is 3.135 V to 3.465 V — compatible with 3.3 V ±5 % rails common in networking and industrial gear.
Package and ordering options
Housed in a 7.00 mm × 5.00 mm, 1.15 mm tall 8-SMD module. The base product number is LMK61PD0A2; the -SIAT suffix denotes the specific frequency/output configuration and packaging variant.
