Product details

156.2935 MHz LVPECL MEMS XO for Industrial Timing

Supply Voltage Range and Enable/Disable Function

Operates from a 2.25 V to 3.63 V supply, covering standard 2.5 V and 3.3 V rails without an external regulator — simplifies power distribution on mixed-voltage boards.

6-VDFN Package and Board Layout

Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint for dense PCB layouts; the 0.90 mm height clears low-profile enclosures and mezzanine card stacks.

Frequently asked questions

What is the difference between DSC1222CI2-156M2935 and DSC1222CI2-125M0000?

Both are from the same DSC12X2 series with identical package, supply range, and temperature grade. The only difference is the output frequency: 156.2935 MHz vs 125.0000 MHz. The LVPECL output, stability, and function pins are the same.

Is DSC1222CI2-156M2935 RoHS compliant?

Yes, the part is listed as RoHS compliant. The 6-VDFN package is lead-free and compatible with standard RoHS reflow profiles.
