Power Supply. Most negative power supply connection.
Power Supply. Most negative power supply connection.
Direct Data Inputs (true and inverse). Pseudo-ECL, differential serial data inputs. They may be
directly driven from true ECL drivers when V
Power Supply. Most positive power supply connection. (Phase Detector, Carrier Detect).
Power Supply. Most negative power supply connection.
ƒ/2 Enable-TTL compatible input used to enable the divide by 2 function.
Power Supply. Most negative power supply connection. (VCO, MUX, Standard Select)
Loop Filter. Node for connecting the loop filter components.
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
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
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
