Product details

What the 133.33 MHz LVPECL output means for the signal chain

The DSC1122BI2-133.3300T is a MEMS-based XO delivering a 133.33 MHz LVPECL output — a differential signal that maintains sharp edges and low jitter over long PCB traces, unlike single-ended LVCMOS which degrades above ~100 MHz.

Supply voltage flexibility and disable function

MEMS resonator advantage over quartz

Typical MEMS oscillators survive 50,000 g shock and 70 g vibration, which makes this part a fit for industrial motor-drive or outdoor telecom enclosures where a quartz can suffers microphonic frequency pulling.

Frequently asked questions

Where can I buy DSC1122BI2-133.3300T?

Buyers need immediate access to purchase the exact part to avoid project delays.

What is the price of DSC1122BI2-133.3300T?

Pricing directly impacts BOM cost, and buyers compare across distributors for best value.

Is DSC1122BI2-133.3300T in stock?

Stock availability determines lead time and can force substitution or delay if out of stock.

What is the datasheet for DSC1122BI2-133.3300T?

Engineers need the datasheet to validate electrical specs and ensure fit in the design.

What is the equivalent or replacement for DSC1122BI2-133.3300T?

When the part is unavailable or obsolete, a cross-reference ensures continuity of supply.

What is the supply voltage range for DSC1122BI2-133.3300T?

Correct voltage is critical for circuit compatibility; mismatch leads to failure.
