Product details

Three fixed clocks from one MEMS resonator

Each output can be configured as HCSL or LVCMOS, giving you the flexibility to drive a PCIe reference clock on one lane and a logic-level clock on another from the same package.

For a 100 MHz carrier, that translates to a maximum drift of ±5 kHz — tight enough for most Ethernet, USB, and general-purpose processor clocks without external trimming. The 2.25 V to 3.6 V supply range covers 2.5 V and 3.3 V rails directly. No extra LDO needed if your board already runs one of those voltages.

Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm footprint, 0.90 mm height).

Frequently asked questions

What output types does DSC400-0414Q0033KE1 support?

Each of the three outputs can be configured as HCSL or LVCMOS. HCSL is typical for PCIe reference clocks; LVCMOS suits general-purpose logic-level clock distribution.

Does DSC400-0414Q0033KE1 have an enable/disable function?

Yes, the enable/disable function allows gating individual outputs without removing the main supply. This is useful for power sequencing or test modes.

What is the closest pin-compatible alternative in the DSC400 family?

The DSC400 family includes many pre-programmed frequency combinations. A different order code within the same DSC400 series will share the same 20-VFQFN footprint and supply range but with a different output frequency set. Confirm the exact frequency plan against your BOM before substituting.
