MB88151APNF-G-100-JNERE1

Clock Generators, PLLs, Frequency Synthesizers Overview

The MB88151APNF-G-100-JNERE1 is a Spread Spectrum Clock Generator designed for EMI reduction. It operates with an input frequency range of 16.6 MHz to 33.4 MHz and provides a multiply-by-1 output frequency range of 16.6 MHz to 33.4 MHz. The device supports center spread modulation rates of ±0.5% and ±1.5%, as well as down spread rates of -1.0% and -3.0%. It functions on a 3.3 V power supply with typical current consumption of 5 mA at 24 MHz. Cycle-cycle jitter is less than 100 ps, and the lock-up time is typically 25 ms.

Clock Generators, PLLs, Frequency Synthesizers FAQ

How is the modulation type selected?

Modulation type (center or down spread) and rate are determined by the logic levels applied to the SEL0 and SEL1 pins.

What is the maximum cycle-cycle jitter?

The cycle-cycle jitter is specified as less than 100 ps under typical operating conditions with no load capacitance.

Can an external clock be used instead of a resonator?

Yes, an external clock can be input to the XIN pin while leaving the XOUT pin open.
