Figure 5-1: GS2975A Typical Application Circuit
NOTE: The GS2975A is drop-in compatible with the GS2975 application circuit. In the
GS2975 application circuit pin 37 is connected to ground. If the GS2975A is dropped into
the GS2975 application circuit, the RCO/DDO1 and RCO/DDO1 pins will output the
recovered clock.
