Product details

The DSC1223BI1-155M5200T is a MEMS-based XO (Standard) from Microchip's DSC1223 series, delivering a 155.52 MHz LVDS output — the exact frequency used in SONET/SDH and 10GbE line cards. It operates from a 2.5V to 3.3V supply rail, drawing 32 mA typical, and includes an Enable/Disable function for power savings when the clock tree is gated.

Housed in a 6-VDFN package measuring 5.00mm x 3.20mm with a seated height of 0.90mm, the footprint matches standard 5x3.2mm oscillator pads — no layout change from quartz-based parts.

Frequently asked questions

What is the frequency and output type of the DSC1223BI1-155M5200T?

It outputs 155.52 MHz with LVDS logic levels. That frequency is standard for SONET/SDH and 10GbE reference clocks.

What supply voltage range does the DSC1223BI1-155M5200T accept?

It operates from 2.5V to 3.3V, covering common 2.5V and 3.3V oscillator supply rails without an external regulator.

Is the DSC1223BI1-155M5200T RoHS compliant?

The part is listed as RoHS compliant per Microchip's standard lead-free finish for the DSC1223 series.
