100 MHz LVDS clock source with MEMS reliability
The DSC1103CI5-100.0000 is a 100 MHz LVDS oscillator built on a MEMS resonator, not a quartz crystal. Maximum supply current is 32 mA in active mode; when the Standby (Power Down) function is asserted, the disable current drops to 95 µA — a meaningful power savings for systems that cycle between active and sleep states.
MEMS vs quartz — what changes for the BOM
A MEMS-based oscillator like this one replaces a quartz crystal + PLL LVDS clock generator in a single 6-SMD, no-lead package measuring 3.20 mm x 2.50 mm x 0.90 mm. The MEMS resonator is inherently more resistant to shock and vibration than a quartz blank, and it eliminates the crystal's startup time and frequency-pull sensitivity to board capacitance. The LVDS output is a direct drop-in for any 100 MHz LVDS oscillator footprint — the same 6-pad layout, same supply range. Confirm the enable/disable logic polarity matches your design; the DSC1103 series uses a Standby (Power Down) function that disables the output and drops current to 95 µA.
Microchip lists the DSC1103CI5-100.0000 as Active. It is available for both new designs and production BOM fills. Sourced through independent distribution; quoted to order against your line-item quantity. No last-time-buy window or successor part number has been issued.
