GC3011 DIGITAL RESAMPLER
6.0 APPLICATION NOTES
6.1 POWER AND GROUND CONNECTIONS
The GC3011 chip is a very high performance chip which requires solid power and ground
connections to avoid noise on the V_CC and GND pins. If possible the GC3011 chip should be mounted on
a circuit board with dedicated power and ground planes and with at least two decoupling capacitors (0.01
and 0.1 µf) adjacent to each GC3011 chip. If dedicated power and ground planes are not possible, then the
user should place decoupling capacitors adjacent to each V_CC and GND pair.
IMPORTANT
The GC3011 chip may not operate properly if these power and ground guidelines are violated.
6.2 STATIC SENSITIVE DEVICE
The GC3011 chip is fabricated in a high performance CMOS process which is sensitive to the high
voltage transients caused by static electricity. These parts can be permanently damaged by static electricity
and should only be handled in static free environments.
6.3 80 MHZ OPERATION
Care must be taken in generating the clock when operating the GC3011 chip at its full 80 MHz clock
rate. The user must insure that the clock is above 2 volts for at least 5 nanoseconds and is below 1 volt for
at least 5 nanoseconds.
6.4 REDUCED VOLTAGE OPERATION
The power consumed by the GC3011 chip can be greatly reduced by operating the chip at the
lowest V_CC voltage which will meet the application’s timing requirements.
