119 / 1350 page  MC9S12XDP512 Data Sheet, Rev. 2.17 Freescale Semiconductor 119 Chapter 3 Pierce Oscillator (S12XOSCLCPV1) 3.1 Introduction The Pierce oscillator (XOSC) module provides a robust, low-noise and low-power clock source. The module will be operated from the VDDPLL supply rail (2.5 V nominal) and require the minimum number of external components. It is designed for optimal start-up margin with typical crystal oscillators. 3.1.1 Features The XOSC will contain circuitry to dynamically control current gain in the output amplitude. This ensures a signal with low harmonic distortion, low power and good noise immunity. • High noise immunity due to input hysteresis • Low RF emissions with peak-to-peak swing limited dynamically • Transconductance (gm) sized for optimum start-up margin for typical oscillators • Dynamic gain control eliminates the need for external current limiting resistor • Integrated resistor eliminates the need for external bias resistor • Low power consumption: — Operates from 2.5 V (nominal) supply — Amplitude control limits power • Clock monitor 3.1.2 Modes of Operation Two modes of operation exist: 1. Loop controlled Pierce oscillator 2. External square wave mode featuring also full swing Pierce without internal feedback resistor |
