50.688 MHz reference for the clock tree
The DSC1101DL2-050.6880T: This frequency is a common multiple for Ethernet PHY reference clocks and high-speed serial interfaces — the 50.688 MHz output saves a PLL multiplication stage on the board.

Frequently asked questions
Where can I buy the DSC1101DL2-050.6880T and check availability?
We source the DSC1101DL2-050.6880T to order against your BOM line.
What is the closest pin-compatible alternative to this oscillator in the DSC1101 family?
The DSC1101 series shares the same 6-VDFN footprint and pinout across its frequency range. A direct alternative would be another DSC1101 order code at the desired frequency — the base product number DSC1101 and package are identical, so a BOM swap requires only a frequency change.
