5 / 13 page 5 of 13 32467 - 0 NOT RECOMMENDED FOR NEW DESIGNS PIN NO SYMBOL TYPE 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 Ω 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 Ω 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 VEE1 Power Supply. Most negative power supply connection.
