MB88151APNF-G-200-JNEFE1

Clock Generators, PLLs, Frequency Synthesizers Overview

The MB88151APNF-G-200-JNEFE1 is a Spread Spectrum Clock Generator manufactured by Infineon Technologies, originally designated as the CY88151A-200. It operates within an input frequency range of 16.6 MHz to 33.4 MHz and provides a multiply-by-2 output frequency ranging from 33.2 MHz to 66.8 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%. Powered by a 3.3 V supply with typical current consumption of 5 mA at 24 MHz, it features cycle-cycle jitter of less than 100 ps-rms. The component is housed in an 8-pin SOP package.

Clock Generators, PLLs, Frequency Synthesizers FAQ

What is the difference between center spread and down spread modes?

Center spread modulates the frequency symmetrically around the nominal frequency, while down spread modulates the frequency only below the nominal frequency to avoid exceeding it.

How is the modulation rate configured?

The modulation rate is set by the logic levels on the SEL0 and SEL1 pins, allowing selection between ±0.5%, ±1.5%, -1.0%, or -3.0%.

What is the maximum cycle-cycle jitter specified for this device?

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