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.","metaTitle":"DSC1033CC1-100.0000 MEMS XO 100 MHz CMOS Obsolete –","metaDescription":"DSC1033CC1-100.0000 is an obsolete 100 MHz MEMS oscillator with CMOS output, ±50 ppm stability, standby function.
