Pierce Oscillator (S12XOSCLCPV2)
12.1
The Pierce oscillator (XOSC) module provides a robust, low-noise and low-power clock source. The
module will be operated from the V
of external components. It is designed for optimal start-up margin with typical crystal oscillators.
12.1.1
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.
12.1.2
Two modes of operation exist:
The oscillator mode selection is described in the Device Overview section, subsection Oscillator
Configuration.

1. Loop controlled Pierce (LCP) oscillator
2. External square wave mode featuring also full swing Pierce (FSP) without internal bias resistor
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 in loop controlled Pierce mode.
Low power consumption:
— Operates from 1.8 V (nominal) supply
— Amplitude control limits power
