GENERAL DESCRIPTION
The AD9523 provides a low power, multi-output, clock distribution
function with low jitter performance, along with an on-chip PLL
and VCO. The on-chip VCO tunes from 3.6 GHz to 4.0 GHz.
The AD9523 is defined to support the clock requirements for
long term evolution (LTE) and multicarrier GSM base station
designs. It relies on an external VCXO to provide the reference
jitter cleanup to achieve the restrictive low phase noise require-
ments necessary for acceptable data converter SNR performance.
The input receivers, oscillator, and zero delay receiver provide
both single-ended and differential operation. When connected
to a recovered system reference clock and a VCXO, the device
generates 14 low noise outputs with a range of 1 MHz to 1 GHz,
and one dedicated buffered output from the input PLL (PLL1).
The frequency and phase of one clock output relative to another
clock output can be varied by means of a divider phase select
function that serves as a jitter-free coarse timing adjustment in
increments that are equal to half the period of the signal
coming out of the VCO.
An in-package EEPROM can be programmed through the serial
interface to store user-defined register settings for power-up
and chip reset.
