DESCRIPTION
18 V
CC2
Power Supply.
Most positive power supply connection. (VCO, MUX, Standard Select).
19
CD
Output
Carrier Detect
. Open collector output which goes HIGH when a signal is present at either the Serial
Data inputs or the Direct Digital inputs. This output is used in conjunction with the GS9000B or GS9000S
in the Automatic Standards Select Mode to disable the 2 bit standard select counter. This pin should
see a low AC impedance (e.g. 1nF to AC Gnd)
20,21
SS0, SS1 Inputs
Standard Select Inputs.
TTL inputs to the 2:4 multiplexer used to select one of four VCO
centre
frequency setting resistors (R
VCO0
- R
VCO3
). When both SS0 and SS1 are LOW, R
VCO0
is selected.
When SS0 is HIGH and SS1 is LOW, R
VCO1
is selected. When SS0 is LOW and SS1 is HIGH, R
VCO2
is selected and when both SS0 and SS1 are HIGH, R
VCO3
is selected. These pins should see a
low AC impedance (e.g. 1nF to AC Gnd)
22,23 SCO/SCO Outputs
Serial Clock Outputs (inverse and true).
Pseudo-ECL differential outputs of the extracted serial clock.
These outputs require a 390
pull-down resistors to V
EE
.
24,25
SDO/SDO Outputs
Serial Data Outputs (inverse and true).
Pseudo-ECL differential outputs of the regenerated serial data.
These outputs require a 390
pull-down resistors to V
EE
.
26
V
CC3
Power Supply.
Most positive power supply connection. (ECL Outputs).
27
V
EE2
Power Supply.
Most negative power supply connection. (Phase Detector, Carrier Detect)
28
V
EE1
Power Supply
. Most negative power supply connection.
