Product details

156.25 MHz reference clock in a 5x3.2 mm QFM package

It is housed in a 6-QFM package (5x3.2 mm) and is intended for surface-mount assembly. This frequency is a common reference for 10 GbE, Fibre Channel, and FPGA/ASIC clock trees where a clean, stable oscillator is needed without external tuning components.

Supply current and thermal margin

The device draws 95 mA typical from the supply rail. In a 6-QFM package with no exposed thermal pad, that 95 mA at 3.3 V (about 314 mW) is dissipated through the board copper.

Frequently asked questions

Is LMK62A2-156M25SIAT active or obsolete?

The part is listed as active by the manufacturer.

Is LMK62A2-156M25SIAT RoHS compliant?

Yes, it is ROHS3 compliant per the manufacturer's status.

What is the closest pin-compatible alternative to LMK62A2-156M25SIAT?

Within the LMK62A2 family, other frequency variants share the same 6-QFM footprint and supply range, but a direct 156.25 MHz pin-compatible drop-in from another manufacturer is not documented in the available records. Check the TI LMK62A2 series for other output frequencies if the 156.25 MHz is not a hard requirement.
