Infineon Technologies MB88151APNF-G-200-JNERE1

Overview

MB88151APNF-G-200-JNERE1 from Cypress Semiconductor is a spread spectrum clock generator (SSCG) designed for EMI reduction in digital systems. It accepts 16.6–33.4 MHz input and outputs 33.2–66.8 MHz (×2 multiplication), supports ±0.5%, ±1.5% center-spread and −1.0%, −3.0% down-spread modulation, operates at 3.3 V ±0.3 V, and delivers <100 ps cycle-cycle jitter - used in PCIe reference clocks and display interface timing.

For engineers reviewing the MB88151APNF-G-200-JNERE1 datasheet, MB88151APNF-G-200-JNERE1 pinout, MB88151APNF-G-200-JNERE1 application, or MB88151APNF-G-200-JNERE1 equivalent, key selection criteria include modulation type configurability, output frequency multiplication ratio, jitter performance under spread mode, power supply tolerance, and SOP-8 thermal and layout compatibility.

Technical Context

The device implements a PLL-based architecture with integrated glitchless IDAC current-output D/A converter for precise analog modulation control. Its modulation logic accepts SEL0/SEL1 binary inputs to select among four discrete spread rates and types, while ENS/XPD enables or disables spreading and provides power-down capability via internal pull-up.

It integrates an on-chip oscillation circuit supporting crystal or external clock input at XIN, with XOUT as buffered resonator output. The CKOUT driver is a CMOS output rated for 4 mA sink current and 40–60% duty cycle, optimized for low-jitter clock distribution in noise-sensitive applications like LCD timing controllers and USB 3.0 PHYs.

FAQ

What is the function of the ENS/XPD pin?

The ENS/XPD pin serves dual functions: when driven high or left floating (due to internal 50 kΩ + 800 kΩ pull-up), it enables spread spectrum modulation; when driven low, it disables spreading and places the device in power-down mode, reducing quiescent current. This pin is not a reset input and does not affect register state.

Can MB88151APNF-G-200-JNERE1 operate with an external clock instead of a crystal?

Yes - apply the external clock to the XIN pin and leave XOUT unconnected (open). The device accepts 16.6–33.4 MHz square-wave or clipped-sine input. Ensure input rise/fall times meet datasheet AC specs and avoid overshoot/undershoot exceeding VDD or VSS ratings to prevent latch-up.

How does the modulation rate selection work with SEL0 and SEL1?

SEL0 and SEL1 are CMOS hysteresis inputs that configure spread type and rate: LL = ±1.5% center, LH = ±0.5% center, HL = −1.0% down, HH = −3.0% down. Configuration is latched on power-up and remains static unless pins are re-driven; no timing sequence or delay is required between changes.

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

Yes - Cypress specifies parallel bypassing: 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 both low-frequency supply droop and high-frequency switching noise, ensuring stable PLL lock and low output jitter.
