Supply flexibility and standby function
The DSC8103CI5: The standby function (pin-controlled) drops the output to high-Z and reduces current consumption to near-zero during system sleep, which matters for battery-backed or power-sensitive designs.
Frequency stability and programmability
Total frequency stability is ±10 ppm across the full operating temperature range and supply voltage variation — tight enough for 1000BASE-T Ethernet and PCIe reference clocks without external tuning. The device ships blank (user must program) via Microchip's field-programmable MEMS process, so the same order code can be programmed to any frequency in the 10 MHz to 460 MHz band, reducing inventory line items.
