Infineon Technologies MB88151APNF-G-200-JNEFE1

Overview

MB88151APNF-G-200-JNEFE1 from Cypress Semiconductor is a spread spectrum clock generator (SSCG) designed to reduce electromagnetic interference in high-speed digital systems. It accepts 16.6–33.4 MHz input and outputs a multiplied-by-2 clock (33.2–66.8 MHz) with programmable center-spread (±0.5%, ±1.5%) or down-spread (−1.0%, −3.0%) modulation, operating at 3.3 V and −40°C to +85°C. Used in PCIe, USB, and display interface timing paths where EMI compliance is critical.

For engineers reviewing the MB88151APNF-G-200-JNEFE1 datasheet, MB88151APNF-G-200-JNEFE1 pinout, MB88151APNF-G-200-JNEFE1 application, or MB88151APNF-G-200-JNEFE1 equivalent, key selection criteria include modulation type configurability, cycle-cycle jitter (<100 ps), CMOS output drive (4 mA), SOP-8 package compatibility, and internal oscillator support for crystal-based or external clock operation.

Technical Context

The MB88151APNF-G-200-JNEFE1 implements a PLL-based architecture with integrated glitchless IDAC modulation control, enabling precise frequency deviation without disrupting clock edges. Its modulation logic responds to SEL0/SEL1 binary inputs and is enabled via ENS/XPD pin with internal 50 kΩ + 800 kΩ pull-up.

It supports both crystal-resonator (XIN/XOUT) and external clock (XIN only, XOUT open) configurations. Output duty cycle is tightly controlled between 40% and 60%, and lock-up time is specified per AC characteristics to ensure stable modulation startup after configuration changes.

FAQ

What crystal frequency range is supported for internal oscillator operation?

The MB88151APNF-G-200-JNEFE1 supports 16.6 MHz to 33.4 MHz crystals connected between XIN and XOUT pins. The device uses these to generate a ×2 output (33.2–66.8 MHz). Crystal load capacitance and series resistance must comply with the manufacturer's recommended values in the oscillator design guidelines to ensure reliable startup and stability across temperature.

Can the modulation be disabled dynamically during operation?

Yes - assertion of logic low on the ENS/XPD pin disables spread spectrum modulation and delivers a low-jitter, unmodulated clock. Because ENS/XPD has an internal pull-up, modulation is enabled by default when left floating or driven high. This allows real-time EMI suppression control without resetting the device or changing other pin states.

Is an external clock source compatible with this device?

Yes - applying a clean, rail-to-rail CMOS clock signal to XIN (with XOUT left open) bypasses the internal oscillator. The device maintains full modulation functionality and output specifications. Input clock must stay within 16.6–33.4 MHz and avoid overshoot/undershoot beyond VDD or below VSS to prevent latch-up per absolute maximum ratings.

How does the device handle power supply decoupling?

The MB88151APNF-G-200-JNEFE1 requires parallel decoupling: a 10 µF electrolytic capacitor and a 0.01 µF ceramic capacitor placed as close as possible between VDD and VSS pins. This dual-capacitor network suppresses low-frequency ripple and high-frequency noise, ensuring stable PLL operation and minimizing modulation-induced supply coupling into the output clock.
