The 61.44 MHz output is a common reference for 10GbE, CPRI, and FPGA SERDES blocks. Supply voltage spans 2.25V to 3.6V, so it runs directly off a 2.5V or 3.3V rail without an intermediate LDO.
6-VDFN package – rework and footprint notes
The 6-VDFN package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a low-profile, small-footprint oscillator. The exposed pad underneath is the thermal and ground plane; make sure the PCB pad has a via array to the ground layer to keep the junction temperature down. Reworking this package is straightforward with hot air — the VDFN has visible side pads and a clear pin-1 chamfer. The small thermal mass means it reflows quickly.
