| Case | 20-VFQFN Exposed Pad |
Supply voltage spans 2.25V to 3.6V, so the oscillator can share a 2.5V or 3.3V rail without a dedicated LDO.
The 20-VFQFN package with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal via pattern under the pad to pull heat into the PCB ground plane. The LVPECL output swings into 50-ohm terminated lines; the DC bias must be set by the receiver's termination network.
Microchip lists the DSC400-2222Q0118KI1T as Active.
