GENERAL DESCRIPTION
The AD9552 is a 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 AD9552 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 AD9552 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 AD9552 is
implemented in a strictly CMOS process.
The AD9552 is specified to operate over the extended industrial
temperature range of −40°C to +85°C.
