FEATURES
Converts a low frequency input reference signal to a high
frequency output signal
Input frequencies from 6.6 MHz to 112.5 MHz
Output frequencies up to 900 MHz
Preset pin programmable frequency translation ratios
Arbitrary frequency translation ratios via SPI port
On-chip VCO
Accepts a crystal resonator and/or an external oscillator
as a reference frequency source
Secondary output (either integer-related to the primary
output or a copy of the reference input)
RMS jitter: <0.5 ps
SPI-compatible, 3-wire programming interface
Single supply (3.3 V)
Very low power: <400 mW (under most conditions)
Small package size (5 mm × 5 mm)
APPLICATIONS
Cost effective replacement of high frequency VCXO, OCXO,
and SAW resonators
Extremely flexible frequency translation with low jitter for
SONET/SDH (including FEC), 10 Gb Ethernet, Fibre
Channel, and DRFI/DOCSIS
High-definition video frequency translation
Wireless infrastructure
Test and measurement (including handheld devices)
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.
