MB88151APNF-G-200-JNERE1

Clock Generators, PLLs, Frequency Synthesizers Overview

The MB88151APNF-G-200-JNERE1 is a Spread Spectrum Clock Generator designed for EMI reduction, manufactured by Infineon Technologies. It operates with a 3.3 V power supply and supports an input frequency range of 16.6 MHz to 33.4 MHz. As a multiply-by-2 variant, it generates an output frequency range of 33.2 MHz to 66.8 MHz. The device features cycle-cycle jitter of less than 100 ps-rms and a typical lock-up time of 25 ms. It consumes 5 mA at 24 MHz under no-load conditions and functions within an operating temperature range of -40 °C to +85 °C. The component is housed in an 8-pin SOP package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Integrates an internal oscillator circuit capable of generating frequencies between 16.6 MHz and 33.4 MHz.
• Provides programmable modulation rates for center spread (±0.5%, ±1.5%) and down spread (-1.0%, -3.0%) via pin settings.
• Utilizes a glitchless IDAC for precise modulation to attenuate unnecessary radiation noise peaks.
• Supports external clock input through the XIN pin while leaving the XOUT pin open.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix JNERE1 against the manufacturer's current ordering guide to confirm packaging type and reliability grade. Check for End-of-Life notifications or product change notices, as this component may have limited availability. Ensure compatibility with the required modulation rate pins SEL0 and SEL1 during procurement planning.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the CY88151A-200 variant when a frequency doubling function is required for inputs between 16.6 MHz and 33.4 MHz. Confirm that the system requires CMOS hysteresis inputs for control pins SEL0, SEL1, and ENS. Verify that the load capacitance on the CKOUT pin does not exceed 15 pF to maintain specified slew rate and duty cycle characteristics.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CY88151A family of Spread Spectrum Clock Generators. It is functionally equivalent to the MB88151A series previously documented by Cypress Semiconductor before integration into Infineon's portfolio. The part number indicates a multiply-by-2 configuration with specific packaging and reliability grading.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct substitutes include other parts from the CY88151A family, such as the CY88151APNF-G-100-JNERE1 for multiply-by-1 applications. Cross-referencing with the MB88151A series is necessary for legacy designs. Ensure any replacement maintains the same SOP-8 package and 3.3 V operating voltage.

Clock Generators, PLLs, Frequency Synthesizers FAQ

How is the modulation type configured?

Modulation type is set using the SEL0 and SEL1 pins. Center spread is selected with LL (±1.5%) or LH (±0.5%), while down spread is selected with HL (-1.0%) or HH (-3.0%).

What is the maximum cycle-cycle jitter specification?

The cycle-cycle jitter is specified as less than 100 ps-rms for both the CY88151A-100 and CY88151A-200 variants under no-load conditions at 25 °C.

How should unused pins be handled?

Unused input pins must not be left open; they should be connected to VDD or VSS using pull-up or pull-down resistors. Unused output pins should be left open.
