Four clocks from one MEMS resonator
Each output can be configured as LVCMOS or LVDS, letting a single oscillator serve mixed-signal clock trees — a 148.25 MHz LVDS pair for a SerDes reference and a 25 MHz LVCMOS for the local processor, all on the same 5.00 x 3.20 mm footprint.
Industrial temperature rating and supply flexibility
The supply range of 2.25 V to 3.6 V covers 2.5 V and 3.3 V rails common in mixed-voltage designs — no additional LDO needed when the core logic runs at 2.5 V and the I/O bank at 3.3 V.
The DSC400 series is the base product number; the -3111Q0088KI2 suffix encodes the factory-programmed frequency plan and output format. Order the exact suffix — the base part alone is not field-programmable.
Housed in a 20-VFQFN with exposed pad (5.00 x 3.20 mm body, 0.90 mm height), the thermal pad must be soldered to a ground-plane island for heat sinking.
