This paper presents a radiation tolerant Phase-Locked Loop (PLL) CMOS ASIC with an optimized Voltage Controlled Oscillator (VCO) for Single-Event Upsets (SEUs). The circuit is designed for high-energy particle physics experiments for low-jitter clock generation and clock recovery. An optimal tuning strategy of the VCO is presented that minimizes the crosssection and the SEU sensitivity of the oscillator. The circuit is processed in a 65 nm CMOS technology and has been irradiated with heavy ions
