Infineon Technologies MB88151APNF-G-500-JNEFE1

Overview

MB88151APNF-G-500-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 66.8 MHz (×1 or ×2), consumes 5 mA typical at 24 MHz, and runs on 3.3 V ±0.3 V across −40 °C to +85 °C in an SOP-8 package.

For engineers reviewing the MB88151APNF-G-500-JNEFE1 datasheet, MB88151APNF-G-500-JNEFE1 pinout, MB88151APNF-G-500-JNEFE1 application, or MB88151APNF-G-500-JNEFE1 equivalent, key selection criteria include modulation type configurability, cycle-cycle jitter <100 ps, CKOUT CMOS drive capability (IOL = 4 mA), and integrated oscillation circuit supporting 16.6–33.4 MHz crystal input.

Technical Context

The MB88151APNF-G-500-JNEFE1 implements a PLL-based spread spectrum architecture with glitchless IDAC modulation control, enabling precise frequency deviation without output glitches. Its internal modulator supports both center-spread and down-spread modes selected via SEL0/SEL1 pins, and features a dedicated ENS/XPD pin for modulation enable or power-down with internal 50 kΩ + 800 kΩ pull-up.

It integrates a full oscillation circuit compatible with parallel-resonant crystals (16.6–33.4 MHz) on XIN/XOUT, delivers CKOUT with 40–60% duty cycle, and maintains low cycle-cycle jitter (<100 ps) even under modulation-critical for timing-sensitive interfaces like PCIe, USB, and DDR clock trees.

FAQ

What crystal specifications are required for MB88151APNF-G-500-JNEFE1?

The device requires a parallel-resonant fundamental-mode crystal rated for 16.6 MHz to 33.4 MHz, with load capacitance of 12 pF to 18 pF, shunt capacitance ≤7 pF, and ESR ≤80 Ω. The crystal must be placed within 5 mm of XIN/XOUT pins, and PCB traces should be symmetric and shielded by ground pour per datasheet layout guidance.

Can MB88151APNF-G-500-JNEFE1 operate without a crystal?

Yes-when an external CMOS clock signal is applied to the XIN pin, the internal oscillator is disabled and XOUT must be left unconnected. The device accepts rail-to-rail 3.3 V logic-level input with 1 ns maximum rise/fall time; overshoot/undershoot must be limited to ±0.3 V to prevent latch-up.

How does ENS/XPD pin behavior differ between modulation enable and power-down modes?

When ENS/XPD is high or open, modulation is active; when pulled low, the device enters power-down mode-stopping CKOUT, disabling modulation, and reducing supply current to <10 µA. The internal 800 kΩ pull-up ensures default modulation on power-up unless actively driven low.

Is MB88151APNF-G-500-JNEFE1 qualified for automotive applications?

While not AEC-Q200 certified as a standalone part, its −40 °C to +85 °C operating range, robust latch-up prevention design, and stable jitter performance under temperature variation make it suitable for non-safety-critical automotive infotainment and telematics modules when validated within the full system EMC and thermal environment.
