Product details

148.5 MHz LVDS clock for video and serial links

This DSC1123AE1-148.5000T is a MEMS-based XO delivering a 148.5 MHz LVDS output — a standard frequency for broadcast video (1080p/3G-SDI) and high-speed serial interfaces like GigE Vision or PCIe reference clocks. The LVDS differential pair gives clean edge rates into 100-ohm terminated traces, reducing jitter compared to a single-ended CMOS oscillator at this frequency. Supply voltage spans 2.25V to 3.63V, so it runs directly off a 2.5V or 3.3V rail without a local LDO.

Active production — no quartz lead-time risk

The MEMS resonator is sourced from Microchip's internal fab, not a quartz blank supplier, so the part avoids the extended lead times that quartz oscillators have seen in recent shortages.

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm.

Frequently asked questions

What is the frequency of the DSC1123AE1-148.5000T?

The oscillator outputs 148.5 MHz LVDS, a standard frequency for 1080p video and 3G-SDI serial digital interfaces.

Is the DSC1123AE1-148.5000T RoHS compliant?

The evidence does not explicitly state RoHS compliance, but Microchip's DSC1123 series is typically RoHS-compliant per their standard material declaration. Confirm with the datasheet or your compliance team.

How does a MEMS oscillator compare to a quartz oscillator for this frequency?

The MEMS resonator eliminates quartz supply constraints and has better shock/vibration tolerance. At 148.5 MHz LVDS, both can meet ±50 ppm stability, but the MEMS part typically has faster startup and no crystal aging drift over the first year.
