The HCSL (High-Speed Current Steering Logic) output is the standard for PCIe reference clocks — the differential swing and common-mode levels match the PCIe Base Spec without external level translation. Absolute Pull Range is ±25 ppm, which covers the spread-spectrum and holdover requirements for PCIe Gen1 and Gen2 reference clocks. In active mode the oscillator draws 42 mA max at 145.2 MHz. This makes the part suitable for gated clock domains where the reference is shut down during system sleep. Housed in a 6-VDFN exposed-pad package measuring 7.00 mm × 5.00 mm with a seated height of 0.90 mm.","metaTitle":"DSC1104AE2-145.2000T – 145.2 MHz HCSL MEMS XO","metaDescription":"Microchip DSC1104AE2-145.2000T: 145.2 MHz HCSL output, ±25 ppm APR, 2.25-3.6V supply, standby function, 6-VDFN package.

The MEMS resonator has a faster startup time (sub-1 ms) and better shock/vibration tolerance than quartz.
