... As an alternative, the GS9010A Automatic Tuning Sub-system and the GS9000B or GS9000S Decoder may be used in conjunction with the GS9015A to obtain adjustment free and automatic standard select operation (see Figure17). With the VCO operating at twice the clock frequency, a clock phase which is centred on the eye of the locked signal is used to latch the incoming data, thus maximising immunity to jitter-induced errors ...

... STAR ROUTED All resistors in ohms, all capacitors in microfarads unless otherwise stated. TEST SETUP Figure 13 shows a typical circuit for the GS9015A using a +5 volt supply. Figure 14 shows the GS9015A connections when using a -5 volt supply. The 0.1 F decoupling capacitors must be placed as close as possible to the corresponding VCC pins. ...

... All resistors in ohms, all capacitors in microfarads unless otherwise stated. VCO Frequency Setting Resistors There are two modes of VCO operation available in the GS9015A depending on the state of the 2 block. The 2 block is enabled according ENABLE = ƒ/2 • SS1. When the ƒ/2 ENABLE (pin 10) is LOW, any of the four VCO ...
