8.0 APPLICATION NOTES
8.1 POWER AND GROUND CONNECTIONS
The GC2011A 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 GC2011A 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
GC2011A 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 GC2011A chip may not operate properly if these power and ground guidelines are violated.
8.2 STATIC SENSITIVE DEVICE
The GC2011A 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.
8.3 106 MHZ OPERATION
Care must be taken in generating the clock when operating the GC2011A chip at its full 106 MHz clock rate.
The user must insure that the clock is above 2 volts for at least 3.6 nanoseconds and is below 0.8 volt for at least 3.8
nanoseconds.
8.4 REDUCED VOLTAGE OPERATION
The power consumed by the GC2011A chip can be greatly reduced by operating the chip at the lowest V_CC
voltage which will meet the application’s timing requirements.
