IGAPLLS14A is a general purpose LC Phase Locked Loop (LCPLL) with external low pass filter capacitor C. 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.
The IGAPLLS14A is LC tank type PLLs. The LC PLL frequency is 291.2MHz. For PVT variation, the PLL have auto frequency calibration function at normal operating mode. Power down mode is available to shut down the power of the PLL circuit.
IGAPLLS14A is designed for TSMC 40nm CMOS Mixed signal RF low power 1.1V/2.5V 1P8M process.
