MB88151APNF-G-500-JNEFE1

Clock Generators, PLLs, Frequency Synthesizers Overview

The MB88151APNF-G-500-JNEFE1 is a spread spectrum clock generator designed for EMI reduction. It features an internal oscillator circuit with a frequency range of 16.6 MHz to 33.4 MHz and operates at a supply voltage of 3.3 V ± 0.3 V. The device provides one CMOS output channel with a maximum output frequency of 16.7 MHz in multiply-by-1 mode. Key electrical parameters include a typical power supply current of 5 mA, cycle-cycle jitter of less than 100 ps-rms, and a lock-up time of approximately 25 ms. It supports center and down spread modulation types via external pin settings.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix JNEFE1 indicates emboss taping (EF type) packaging as defined in the official documentation. Confirm that the component status aligns with current Infineon or Cypress product lifecycle notifications, as legacy clock generators may have specific availability constraints. Ensure compatibility with existing PCB footprint requirements for the SOP-8 package.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when EMI attenuation is required without external modulators. Choose the multiply-by-1 variant if the output frequency must match the input range of 16.6 MHz to 33.4 MHz. Verify that the required modulation rate (±0.5%, ±1.5%, -1.0%, or -3.0%) can be achieved using the available SEL0/SEL1 pin configurations. Ensure the load capacitance on CKOUT does not exceed 15 pF for optimal slew rate performance.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CY88151A family of spread spectrum clock generators, originally developed by Cypress Semiconductor and later integrated into Infineon Technologies' portfolio. The MB88151 prefix represents the prior naming convention used before the full brand integration. The device serves as a direct replacement for older MB88151 series components with updated packaging options.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include CY88151APNF-G-100-JNEFE1 for identical functionality with standard emboss taping. For multiply-by-2 applications requiring higher output frequencies, consider CY88151APNF-G-200-JNEFE1. Ensure pinout compatibility remains consistent across the CY88151A family variants.
