时钟发生器带旁路CMOS，晶体CMOS，LVDS，LVPECL

Overview

The AD9552BCPZ is an Oscillator Frequency Upconverter for use with high-definition video frequency translation. The fractional-N phase locked loop (PLL) based clock generator designed specifically to replace high frequency crystal oscillators and resonators. The device employs a sigma-delta (Σ-Δ) modulator (SDM) to accommodate fractional frequency synthesis. The user supplies an input reference signal by connecting a single-ended clock signal directly to the REF pin or by connecting a crystal resonator across the XTAL pins. The AD9552BCPZ is pin programmable, providing one of 64 standard output frequencies based on one of eight common input frequencies. The device also has a 3-wire SPI interface, enabling the user to program custom input-to-output frequency ratios. The AD9552BCPZ relies on an external capacitor to complete the loop filter of the PLL. The output is compatible with LVPECL, LVDS or single-ended CMOS logic levels, although the AD9552BCPZ is implemented in a strictly CMOS process
