EVALUATION BOARD HARDWARE
Figure 1 shows the ADAR1000-EVALZ, with 13 high frequency
connectors for the four transmit outputs, four receive inputs,
four detector inputs, and a common RF input and output. Four
on-board banana jacks provide power supply connections and a
connector for an SDP adapter board that interfaces with the
USB on a Windows-based PC. Dual row, square pin headers allow
connections to four transmit and receive modules, as well as the
daisy-chaining of up to four ADAR1000-EVALZ boards together.
The ADAR1000-EVALZ requires an
adapter
board to program the device. The ADAR1000-EVALZ evaluation
software and the examples provided in this user guide both make
use of this SDP connection. The SDP adapters are not included
with the ADAR1000-EVALZ, but these adapters are available
through local Analog Devices distributors, as well as on the
product page.
The interface signals on the
core chip, plus additional
digital interface circuitry, are made available on the ADAR1000-
EVALZ, as shown in Figure 2.
POWER SUPPLY REQUIREMENTS
The ADAR1000-EVALZ is powered via two external supplies
(see Table 1). Connections to the ADAR1000-EVALZ are
described in the Quick Test Procedure section. Note that the
−3.3 V banana jack has no function and therefore is not populated.
