When used as an OUTPUT, the CD/Mute pin will provide an
indication of the output mute status. The CD/Mute voltage
will fall to below 1.2V when the carrier is present and the
data outputs are active.
NOTE: The CD/Mute pin is not functional in BYPASS mode.
4. APPLICATION REFERENCE DESIGN
4.1 PCB LAYOUT
An FR-4 dielectric can be used, however, controlled
impedance transmission lines are required for PCB traces
longer than approximately 1cm. Note the following PCB
artwork features used to optimize performance:
1. The PCB ground plane is removed under the GS9064
input AND output components to minimize parasitic
capacitance.
2. High speed traces are curved to minimize impedance
changes.
4.2 TYPICAL APPLICATION CIRCUIT
5. REFERENCES
Compliant with SMPTE 259M and SMPTE 344.
