This frequency is a common reference for 10 Gigabit Ethernet (10GBASE-R) and other high-speed serial data links where the line rate is a multiple of 156.25 MHz. ## Supply and power budget The oscillator operates from a 3.135 V to 3.465 V supply rail, drawing 162 mA typical. This current draw is the dominant term in the oscillator's power budget; the total dissipation at 3.3 V is roughly 535 mW, which the 7x5 mm QFM package's exposed pad must conduct to the PCB ground plane. The narrow supply tolerance (3.3 V ±5 %) means the rail must be regulated — not a raw battery or unregulated bus. ## Industrial temperature range and package The 6-SMD Module package (Supplier Device Package 6-QFM 7x5) has a 7x5 mm footprint with an exposed thermal pad. ## Active lifecycle and sourcing The part is sourced through authorized distribution channels.","metaTitle":"Texas Instruments LMK60E0-156257SIAR Clock Oscillator","metaDescription":"Texas Instruments LMK60E0-156257SIAR clock oscillator, 156.257 MHz, 6-QFM package, -40 to 85°C.
