Output 1 runs at 14.7456 MHz, a common baud-rate generator frequency for UART and serial interfaces; Output 2 provides 148.5 MHz, the standard pixel clock for 1080p video at 60 Hz.
Operating from 2.25V to 3.6V, the oscillator spans 2.5V and 3.3V logic rails without a level translator — one BOM line covers both domains.
Output 1 is 14.7456 MHz; Output 2 is 148.5 MHz. Both are LVCMOS.
Functionally yes — it provides the same LVCMOS output as a quartz XO, but the MEMS resonator inside is more resistant to vibration and has a faster startup time. The 20-VFQFN package is not pin-compatible with a standard 4-pad 5x3.2 mm quartz oscillator; a PCB layout change is required.
