Product details

156.25 MHz LVPECL clock source for high-speed interfaces

With ±50 ppm frequency stability and a supply voltage range of 2.5V to 3.3V, this oscillator covers the common core and I/O rails for most networking and communications ASICs.

Active production — no lifecycle concern

The 6-VDFN package (2.50mm x 2.00mm, 0.90mm seated height) is a standard surface-mount footprint that places cleanly with no tombstoning risk, and the Enable/Disable pin lets a system controller gate the clock without a separate buffer.

Frequently asked questions

What is the function of the Enable/Disable pin on the DSC1222DL1-156M2500T?

The Enable/Disable pin allows a logic-level signal to gate the LVPECL output. When disabled, the output enters a high-impedance state, which lets multiple oscillators share a clock line or lets a system controller power down the clock tree without removing the supply rail.

What voltage range does the DSC1222DL1-156M2500T support, and is it compatible with 3.3V?

The supply voltage range is 2.5V to 3.3V, so it works directly on a 3.3V rail without an external regulator. The LVPECL output levels scale with the supply, so the receiver must be rated for the same Vcc.

Is there a pin-compatible alternative to the DSC1222DL1-156M2500T in the DSC12X2 family?

The DSC12X2 series shares the same 6-VDFN footprint and pinout across multiple frequency and stability options. For a different frequency or tighter stability, another member of the DSC12X2 family can be substituted without a board layout change — confirm the output type (LVPECL) and supply voltage match.
