Product details

LVPECL is a differential, DC-coupled logic level that requires 50-ohm termination to VCC – 2 V at the receiver. The 18.432 MHz frequency is a common multiple for 10/100/1000BASE-T Ethernet, PCIe reference clocks, and serial transceiver PLLs.

Supply voltage range and power budget

The supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V rails without an external regulator.

Package and board layout notes

The 6-SMD no-lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The 0.197" x 0.126" footprint matches industry-standard 5x3.2 mm oscillator pads.

Frequently asked questions

Is DSC1122BE2-018.4320T RoHS compliant?

The evidence does not list a specific RoHS compliance statement. The part is a standard MEMS oscillator in a 6-SMD no-lead package; verify the latest RoHS status on the Microchip DSC1122 series product page or request a certificate of compliance with your order.
