Working principle of ISPPAC-CLK5510V-01T48I

The ISPPAC-CLK5510V-01T48I is a highly integrated clock synthesizer providing control of both crystal and internal clock oscillator parameters. The device integrates a four-phase output clock generator and a PWL-programmable frequency synthesizer that operates from a reference clock. The frequency synthesizer consists of two independent phase-locked loops (PLLs). The PLLs are used to provide the phase control signals to drive the four phase output clock generator.

The device provides two 8-bit I2C-programmable and one 8-bit SPI-programmable slices to program the device. The I2C slices can be used to program the frequency synthesizer for reference/clock input selection and to program the PLL parameters. The SPI slice can be used to program the clocking parameters of the output clock generator. The device also provides an internal spread-spectrum generator which can be used to reduce electromagnetic interference (EMI).

The device also provides 16 hardware adjustment pins to adjust the phase, duty cycle, frequency, and spread spectrum of the device. The hardware adjustment pins are used to precisely skew and spread the clock outputs to address system EMI challenges. The device provides two differential external clock inputs, which can be used to reduce the jitter of the outputs and meet stringent system requirements.
