Product details

364 MHz LVPECL clock source for high-speed logic

Supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without a separate regulator.

Frequency stability and temperature grade

Rated ±10 ppm frequency stability over the -20°C to 70°C commercial range — tight enough for most 10GbE and 12G-SDI reference clocks, but the temperature ceiling means this oscillator stays in indoor, conditioned equipment. An outdoor base-station or engine-bay application would need the industrial-temperature sibling from the DSC1122 family.

No last-time-buy window to chase, no forced redesign for a drop-in replacement. The DSC1122 series is Microchip's current MEMS oscillator platform, so supply continuity is baked into the product line.

6-SMD no-lead package, 3.20 mm x 2.50 mm footprint, 0.90 mm seated height. The LVPECL output is a differential pair — route the two traces as a controlled-impedance 100-Ω differential pair with the termination resistors placed close to the receiver. The Enable pin is active-high; leave it pulled high if the function is unused.

Frequently asked questions

Does the DSC1122CE5-364.0000T have a direct replacement or equivalent?

No direct replacement or second-source is listed for this order code. The DSC1122 series is Microchip's own MEMS oscillator family; if you need a different frequency or stability, the same base part number DSC1122 covers a range of options. For a pin-compatible alternative, check other DSC1122CE5 variants with the same 6-SMD package and LVPECL output.

Is the DSC1122CE5-364.0000T compatible with a 2.5V supply?

Yes. The supply voltage range is 2.25V to 3.6V, so a 2.5V rail is within spec. The LVPECL output levels scale with the supply voltage — at 2.5V the swing is reduced compared to 3.3V, but the differential signal still meets the receiver's common-mode range for most LVPECL inputs.
