System Functions
Analog In
The Analog In pin accepts the analog input. It is internally
biased so that the input signal may be either AC or DC cou-
pled, as long as it does not exceed the positive supply volt-
age. Proper input coupling is illustrated below.

FIGURE 1. ANALOG IN
The CD22202 and CD22203 are designed to accept sinusoi-
dal input waveforms, but will operate satisfactorily with any
input that has the correct fundamental frequency with har-
monics that are at least 20dB below the fundamental.
Crystal Oscillator
The CD22202 and CD22203 contain an on-board inverter
with sufficient gain to provide oscillation when connected to
a low cost television “color-burst” (3.579545MHz) crystal.
The crystal oscillator is enabled by tying XEN high. The crys-
tal is connected between XIN and XOUT. A 1M
Ω resistor is
also connected between these pins in this mode. ATB is a
clock frequency output. Other CD22202 and CD22203
devices may use the same frequency reference by tying
their ATB pins to the ATB output of a crystal connected
device. XIN and XEN of the auxiliary devices must then be
tied high and low, respectively. Up to ten devices may be run
from a single crystal connected CD22202 and CD22203 as
shown in Figure 2.
