RVCO1
Input
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 VEE.
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 VEE.
15
RVCO2
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 VEE.
16
VEE3
Power Supply. Most negative power supply connection.
17
RVCO3
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 VEE.
