148.5 MHz LVDS oscillator for precision timing
The DSC1103CI5-148.5000 is a MEMS-based XO (Standard) oscillator delivering an LVDS output at 148.5 MHz — the exact frequency used in broadcast video (SMPTE 274M/296M) and high-speed serial links. The ±10 ppm frequency stability keeps the jitter budget tight enough for 12G-SDI or 10-Gigabit Ethernet reference clocks without an external VCXO.
The 6-SMD no-lead package (3.20 mm x 2.50 mm, 0.90 mm seated height) is a common footprint shared across the DSC1103 family — the PCB pad layout is the same as for other 3.2 x 2.5 mm MEMS oscillators, simplifying second-sourcing.
The MEMS base resonator means there is no quartz crystal to age or shock-damage — the die-level cavity is sealed at wafer fab, which improves long-term reliability in vibration-prone installations.
