Product details

150 MHz LVPECL clock source for industrial and telecom

Supply voltage spans 2.25V to 3.6V, so it runs directly from a 2.5V or 3.3V rail without an intermediate LDO; the wide tolerance also absorbs rail droop during load transients.

MEMS resonator advantage over quartz

Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — the compact footprint suits dense PCB layouts, but the LVPECL output requires controlled-impedance differential traces (typically 100 Ω differential) and AC-coupling to the receiver if the DC common-mode voltage differs.

Frequently asked questions

Can the DSC1122CI2-150.0000 replace an older quartz oscillator in my design?

Yes, if the existing quartz oscillator is a 150 MHz LVPECL device in a 6-SMD no-lead footprint with a 2.25V–3.6V supply. The MEMS base offers better shock/vibration immunity than quartz, but confirm the Enable/Disable logic polarity and the output load termination (LVPECL requires DC biasing or AC-coupling) match your receiver. No pin-compatible alternative is listed on the same DSC1122 series — the DSC1122CI2-150.0000 is the exact order code for this frequency and output.

What is the frequency output of the DSC1122CI2-150.0000?

The output frequency is 150 MHz with an LVPECL differential signal type.
