The DSC8103BI2: The standby function (pin-controlled) drops the output and reduces current draw — useful for battery-powered or sleep-mode systems where every milliwatt counts.
Temperature range and stability
That's tight enough for most serial links (USB, 100BASE-TX, CAN) without needing a TCXO.
Package and hand-solderability
The footprint is standard and hand-solderable with a fine-tip iron or hot air — no special equipment required for prototyping.
Programming note
This variant ships as a blank (user must program) — you'll need to order it pre-programmed to your desired frequency or use a Microchip programmer. The base product number DSC8103 covers the whole family; the BI2 suffix indicates the specific blank, LVDS, -40°C to 85°C option.
