Product details

156.2539 MHz LVPECL clock source

The DSC1122BI2-156.2539 outputs a 156.2539 MHz LVPECL differential signal, a standard for high-speed serial links where low jitter and tight skew are required.

MEMS resonator and supply flexibility

The supply voltage range of 2.25V to 3.6V lets the same ordering code serve designs with 2.5V or 3.3V rails without a separate voltage variant.

Enable/Disable function and package

The 5.00 mm x 3.20 mm package (0.90 mm seated height) is a common footprint for high-frequency oscillators and fits standard reflow assembly.

Active lifecycle and ordering

The base product number DSC1122 covers the full frequency and stability family; confirm the exact suffix for your target frequency and stability grade.

Frequently asked questions

What is the closest pin-compatible alternative to the DSC1122BI2-156.2539?

Within the DSC1122 series, the same 6-SMD footprint and pinout is shared across all frequency and stability variants. For a different frequency or tighter stability, order the matching DSC1122 suffix. No direct second-source from another manufacturer is documented on this specific order code.
