100 MHz HCSL clock source for FPGA and SerDes reference
The DSC1104DI2-100.0000 is a 100 MHz HCSL (High-Speed Current Steering Logic) oscillator from Microchip's DSC1104 MEMS family. HCSL is the standard reference for PCIe Gen1/2/3, SATA, and many FPGA clock inputs — the differential swing and common-mode voltage match the receiver's input threshold without external level shifting.
Standby function and power-down current
A standby (power down) pin disables the output and reduces current consumption to 95 µA max. This is useful for battery-operated systems that gate the clock tree during sleep modes — the oscillator wakes in microseconds, faster than a quartz crystal startup. Active supply current is 42 mA max at 100 MHz, which is typical for a differential-output MEMS oscillator at this frequency.
6-VDFN package and PCB footprint
The 6-VDFN package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The 0.50 mm pitch pads require a fine-pitch soldering profile and a solder-mask-defined pad on the PCB. Surface-mount assembly with standard reflow profiles; the MEMS resonator is inherently more shock-tolerant than quartz, making this a fit for portable and industrial applications.
