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 VCC 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 VCC 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 VCC

voltage which will meet the application’s timing requirements.
