Product details

100 MHz HCSL clock — active production, industrial temp grade

The DSC1104BI5-100.0000 is an active-production XO (Standard) from Microchip's DSC1104 series, delivering a 100 MHz HCSL output from a MEMS resonator. HCSL is the differential clock standard for PCIe reference clocks — the 100 MHz frequency is the PCIe base rate, making this a drop-in clock source for PCIe Gen1/2/3 root complexes and switches.

Standby power-down and supply budget

Package footprint and board-level fit

The 5.00 mm x 3.20 mm 6-SMD no-lead package (0.90 mm seated height) is the standard 5x3.2 mm oscillator footprint — the same land pattern used by many quartz and MEMS oscillators. No via-in-pad required; the four corner pads are the supply and output pins, with the two centre pads as NC or GND depending on the function variant.

Frequently asked questions

What does the standby (power down) function do on this oscillator?

When the standby pin is asserted (typically low), the internal MEMS resonator and output driver are disabled. The output goes to high-impedance, and the supply current drops from 42 mA max to 95 µA max. This lets the system gate the clock tree without an external load switch, preserving battery life during sleep modes.

What is the frequency stability of the DSC1104BI5-100.0000?

The frequency stability is ±10 ppm, which includes the effects of temperature, supply voltage variation, and aging over the -40 to 85°C operating range. That is tight enough for most Ethernet and PCIe clocking requirements without external trimming.
