148.35 MHz LVDS clock source — what it replaces
That frequency lands in the range used for 10G Ethernet MAC/PHY reference clocks, FPGA transceiver reference inputs, and high-speed ADC/DAC sampling clocks — any link where a clean differential clock saves you from single-ended jitter.
Supply rails and output — what the board needs
The 7.00 mm x 5.00 mm, 0.90 mm seated height package is the common 7x5 mm LVDS oscillator footprint — the exposed pad on the bottom is not electrically connected but should be soldered to a ground-plane island for thermal relief. Fine for indoor networking gear, test equipment, and server motherboards. Not rated for outdoor telecom cabinets or engine-bay electronics.
