Product details

The DSC1103BI2-148.5000 is a MEMS-based XO (Standard) oscillator delivering a 148.5 MHz LVDS output — the exact frequency used in 3G-SDI and 1080p video clocking. The LVDS differential pair keeps noise coupled into the clock path low over long PCB traces, which matters when the oscillator sits on a separate board from the FPGA or serializer. The wide tolerance also absorbs ripple from a switching regulator without degrading the ±25 ppm frequency stability.

Industrial temperature range and standby function

For battery-powered equipment that sleeps between transmissions, this saves enough power to extend field life without a separate load switch.

Frequently asked questions

Is the DSC1103BI2-148.5000 compatible with 3.3V logic?

Yes. The supply voltage range of 2.25 V to 3.63 V covers both 2.5 V and 3.3 V rails. The LVDS output is a differential pair that meets the LVDS standard (typical 1.2 V common-mode, 350 mV swing), so it interfaces directly with 3.3 V LVDS receivers without level translation.

What is the frequency stability of the DSC1103BI2-148.5000?

The frequency stability is ±25 ppm over the full operating temperature range and supply voltage variation. For a 148.5 MHz carrier, ±25 ppm corresponds to a maximum frequency error of about 3.7 kHz — well within the tolerance of most video and data-recovery PLLs.
