R
VCO0
Input
VCO Resistor 0.
Analog current input used to set the centre frequency of the VCO when the two
Standard Select bits (pins 20 and 21) are set LOW. A resistor is connected from this pin to V
EE
.
14
R
VCO1
Input
VCO Resistor 1.
Analog current input used to set the centre frequency of the VCO when Standard
Select bit 0 (pin 20) is set HIGH and bit 1 (pin 21) is set LOW. A resistor is connected from this pin to V
EE
.
15
R
VCO2
Input
VCO Resistor 2.
Analog current input used to set the centre frequency of the VCO when Standard
Select bit 0 (pin 20) is set LOW and bit 1 (pin 21) is set HIGH. A resistor is connected from this pin to V
EE
.
16 V
EE3
Power Supply
. Most negative power supply connection.
17 R
VCO3
Input
VCO Resistor 3.
Analog current input used to set the centre frequency of the VCO when the two
Standard Select bits (pins 20 and 21) are set HIGH. A resistor is connected from this pin to V
