Infineon Technologies MB88151APNF-G-100-JNEFE1

Overview

MB88151APNF-G-100-JNEFE1 from Cypress Semiconductor is a spread spectrum clock generator (SSCG) designed for EMI reduction in digital systems. It modulates output frequency with ±0.5% or ±1.5% center-spread and −1.0% or −3.0% down-spread modes, operates from 16.6 MHz to 33.4 MHz input/output (×1), consumes 5 mA typical at 24 MHz, and runs on 3.3 V ±0.3 V across −40 °C to +85 °C in SOP-8 package.

For engineers reviewing the MB88151APNF-G-100-JNEFE1 datasheet, MB88151APNF-G-100-JNEFE1 pinout, MB88151APNF-G-100-JNEFE1 application, or MB88151APNF-G-100-JNEFE1 equivalent, key selection factors include modulation type configurability via SEL0/SEL1 pins, low cycle-cycle jitter (<100 ps), CMOS-compatible CKOUT output drive (4 mA sink), internal oscillator support, and ENS/XPD dual-function enable/power-down control.

Technical Context

The MB88151APNF-G-100-JNEFE1 implements a PLL-based spread spectrum architecture with glitchless IDAC modulation control, enabling precise frequency deviation without output discontinuities. Its modulation logic accepts two binary inputs (SEL0/SEL1) to select among four discrete spread profiles, while ENS/XPD pin enables or disables modulation and supports power-down mode with internal 50 kΩ + 800 kΩ pull-up.

It integrates an on-chip oscillator circuit supporting 16.6–33.4 MHz crystal or ceramic resonator operation between XIN and XOUT pins, and delivers a CMOS-level CKOUT signal with 40–60% duty cycle and <100 ps cycle-cycle jitter. No external loop filter components are required due to integrated charge pump and loop filter.

FAQ

What modulation profiles does MB88151APNF-G-100-JNEFE1 support?

MB88151APNF-G-100-JNEFE1 supports four discrete modulation profiles: ±0.5% and ±1.5% center-spread, and −1.0% and −3.0% down-spread. These are selected statically using the logic states of SEL0 and SEL1 pins (L/L, L/H, H/L, H/H respectively). No external programming or I²C interface is required - configuration is hardware-defined at power-on.

Can MB88151APNF-G-100-JNEFE1 operate with an external clock instead of a crystal?

Yes. When using an external clock, apply it to the XIN pin and leave the XOUT pin unconnected (open). The device will bypass its internal oscillator and use the applied clock as the reference. Ensure the external clock meets voltage swing (CMOS-compatible), rise/fall time (<5 ns), and noise specifications to avoid metastability or lock failure.

How does the ENS/XPD pin function in power-down mode?

When ENS/XPD is driven low, MB88151APNF-G-100-JNEFE1 disables modulation and enters power-down mode, reducing supply current to near-zero (typically <1 µA). The pin has an internal 50 kΩ + 800 kΩ pull-up network, so leaving it unconnected defaults to modulation enabled. This dual functionality allows hardware-controlled EMI gating without additional logic.

Is a bypass capacitor required on VDD, and what value is recommended?

Yes. Cypress specifies a parallel bypass network: a 10 µF electrolytic capacitor and a 0.01 µF ceramic capacitor placed as close as possible between VDD and VSS pins. This combination suppresses both low-frequency supply ripple and high-frequency switching noise, ensuring stable PLL operation and minimizing modulation distortion and jitter.
