The DSC2033FI2-F0003T delivers two identical 150 MHz LVDS outputs from a single MEMS resonator, eliminating a second oscillator when a design needs a differential clock pair for a dual-lane SERDES or two independent PLLs. LVDS signaling keeps the 150 MHz edges clean across a few inches of FR4 trace—no single-ended noise coupling into adjacent analog supplies.
LVDS, differential. Both outputs (Frequency 1 and Frequency 2) are 150 MHz LVDS. The AC-coupled termination at the receiver should be 100 Ω across the pair.
Yes—the supply range is 2.25V to 3.6V. A 2.5V rail is within spec, and the LVDS output common-mode voltage adjusts automatically with VDD.
The evidence does not list DSC2033FI2-F0002T specifications, so a direct pin-to-pin replacement cannot be confirmed. Both share the same base product number DSC2033, but the frequency and stability options differ by the suffix. Verify the output frequency and stability of the original before substituting.
