212.5 MHz fixed-frequency XO for the clock tree
The LMK60E0-212M50SIAR: This is the core reference for a SerDes, FPGA transceiver bank, or high-speed ADC/DAC clock — the 212.5 MHz rate is a common multiple for 10G Ethernet and CPRI line rates, so it fits directly into baseband and optical transport designs without an external PLL multiplier. The part draws 95 mA typical from the supply, which sets the thermal budget for the local LDO or power rail.
Industrial temp range and board-fit
The 6-SMD Module footprint (6-QFM, 7 mm × 5 mm) uses a standard QFN-style land pattern with an exposed center pad. Reflow profile follows standard lead-free SAC305 with a peak temperature around 260°C; no special moisture sensitivity level is stated, but a bake before reflow is prudent if the reel seal is broken.
Active lifecycle — sourcing posture
The base product number LMK60E0 covers the family; the full suffix SIAR encodes the frequency, supply tolerance, and tape-and-reel packaging — confirm the BOM line specifies the exact suffix before committing the order.
