The 49.152 MHz frequency is a common multiple for audio sample rates (48 kHz × 1024) and video pixel clocks, making this oscillator a natural fit for audio/video bridging, HDMI, and Ethernet PHY reference clocks. ## Supply voltage and output control Operating from 2.25V to 3.6V, this oscillator covers both 2.5V and 3.3V logic rails without an external regulator — a single supply rail serves the entire clock tree. The 6-VDFN package measures 5.00mm x 3.20mm with a seated height of 0.90mm — a compact footprint for space-constrained PCBs, but the exposed pad requires a thermal via pattern and solder-paste stencil design to avoid voids.
