IGAPLLV12A is a general-purpose Phase-Locked Loop (PLL) with external low pass filter capacitor C (1.5 nF). It is designed to provide a stable and accurate clock for high speed and high resolution ADC. This PLL IP optimizes the phase jitter performance with the limited current consumption.
IGAPLLV12A is LC tank type PLLs. The LC PLL frequency is 7.219 GHz in usual case. The PLL incorporates several frequency dividers to generate various output frequencies for different applications. For PVT variation, the PLL has auto frequency calibration function in normal operating mode. The power-down mode is available to shut down the power of the PLL circuit. The bypass mode provides to bypass the output clock of PLL to the external reference clock.
IGAPLLV12A is designed for TSMC CLN12FFC 0.8 V/1.8 V process.
