Triple-frequency HCSL clock in a single MEMS XO
The DSC2044FE1-H0003 is a MEMS-based XO (Standard) that outputs three common reference clocks — 100 MHz, 125 MHz, and 156.25 MHz — on a single HCSL output, covering PCIe Gen1/2/3 and 1Gb/10Gb Ethernet reference frequencies without a separate PLL or fanout buffer.
Package, footprint, and temperature grade
Housed in a 14-VFQFN Exposed Pad package measuring 3.20 mm x 2.50 mm with a height of 0.90 mm, the DSC2044FE1-H0003 fits tight networking line-card layouts; the exposed paddle requires a thermal via pattern under the pad for proper soldering and thermal relief.
