OPERATION WHEN IN TEST MODE
If the test 1 terminal (pin 1) is set to high level, this will be test mode.
There are three kinds of test modes as follows :
Mode l, Mode 2
In mode 1 and 2, a test to inspect the PLL lock condition is executed. After inputting data to
the main counter and swallow counter by means of the method indicated in the diagram 2, the
test 1 terminal (pin 1) will be set to high level while the enable terminal (pin 2) is held to low
level. In this condition, a comparating frequency signal is output to the clock terminal (pin 4)
and a main counter division signal to the data terminal (pin 3).
The method of inputting to a divider has two kinds : mode 1 and mode 2.
Mode 1. This is the method of inputting from the RF input terminal (pin 15) by setting the
lock terminal (pin 20) to high level.
The lock condition in normal use operation can be inspected using this method.
Mode 2. This is the method of directly inputting to a 1/32 and 1/33 divider from the test
2 terminal (pin 19) without passing through a 1/8 prescaler by setting the lock
terminal (pin 20) to low level.
Mode 3
In mode 3, a prescaler, phase comparator, and charge pump will be tested.
If both test 1 terminal (pin 1) and enable terminal (pin 2) are set to high level, these will be in
mode 3. The clock terminal (pin 4) will be comparison reference frequency signal input of phase
comparator, the data terminal (pin 3) is a comparated frequency signal input, and the lock
terminal (pin 20) is a prescaler output (the fixed dividing ratio of 1/256).
The output polarity of phase comparator is as follows :

THE METHOD OF INPUTTING DATA
The method of inputting data will be indicated in the diagram 1.
LOCK FREQUENCY CALCULATION METHOD
The lock frequency can be calculated in the following formula :
fosc=frx8x(32M +S)
fOSC : The oscillation frequency of VCO (the input frequency of prescaler)
64M Hz: fOSC X'tal = 4M Hz
fr : Reference frequency ; it will be 1/512 of oscillation frequency of a crystal oscillator.
When a 4MHz crystal oscillator is used, this will be fr=7.8125kHz and the lock frequency
step will be 62.5kHz.
M : Preset value of Main counter ; The 9 bits between MSB to MSB-8.
Input 32S: MS 511 value in binary.
S : Preset value of Swallow counter ; The 5 bits between MSB-9 to LSB.
Input os rs 31 value in binary.
For example, when fosc=801MHz is received at the reference frequency of 7.8125kHz,
801 x103=7.8125x8x(32M+S)
32M +S= 12816
M =400 (10) = 110010000 (2)
S = 16 (10) = 10000 (2)
