The digital data are differentially terminated on-board (100
Ω) however, they can be
probed either in differential or in single-ended mode.
5.
Connect the ADC and DMUX function jumpers.
All instrumentation and connectors are now connected.
6.
Switch on the power supplies (recommended power up sequence: simultaneous
or in the following order: V
EE
= -5V and -5V, then V
MINUSD
= -2.2V, and finally
V
CCA
= 3.3V, V
CCD
= 3.3V, 3.3V and V
PLUSD
= 2.5V).
7.
Switch on the RF clock generator.
8.
Switchon the RF signal generator.
9.
Perform an asynchronous reset (ASYNCRST push button) on the device.
The AT84AS003-EB evaluation board is now ready for operation
Note:
1. Absolute maximum ratings are short term limiting values (referenced to GND = 0 V), to be applied individually, while other
parameters are within specified operating conditions. Long exposure to maximum ratings may affect device reliability.
2. All integrated circuits have to be handled with appropriate care to avoid damage due to ESD. Damage caused by inappropri-
ate handling or storage could range from performance degradation to complete failure
