Product details

The DSC1033CC1-100.0000 is a 100 MHz XO (Standard) oscillator built on a MEMS resonator, delivering a CMOS output at 3.3 V supply. It belongs to Microchip's PureSilicon™ series and comes in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm.

Microchip lists the DSC1033CC1-100.0000 as Obsolete. For existing BOM lines, this part is available through independent surplus channels. The 4-SMD package and 100 MHz CMOS output mean a pin-compatible drop-in from another manufacturer would require the same footprint and supply voltage.

Frequency stability and temperature grade

For a 100 MHz clock, ±50 ppm translates to a maximum frequency error of ±5 kHz — well within the tolerance of most Ethernet PHYs and FPGA reference inputs, but the 0°C lower limit means this part should not be used in unheated outdoor enclosures or cold-start automotive environments.

Frequently asked questions

What is the replacement for the DSC1033CC1-100.0000?

No official successor is listed by Microchip for this exact order code. A functionally equivalent 100 MHz MEMS oscillator with CMOS output and 3.3 V supply in a 4-SMD package would be the closest substitute, but pin compatibility must be verified against the original footprint.
