Evaluation Board for FSK AD5700/AD5700-1 HART Modem
FEATURES
GENERAL DESCRIPTION
Convenient connections for power through screw
Terminal block
Use of on-chip RC oscillator or an external crystal
Various link options
This user guide describes the evaluation board for the AD5700/
AD5700-1 Highway Addressable Remote Transducer (HART®)
modem. This board can be used to evaluate either the AD5700
or the AD5700-1 part. Both can operate from a single 1.71 V to
5.5 V supply, with the AD5700-1 having the added feature of
an integrated oscillator.
EQUIPMENT NEEDED
Host controller with UART interface
Complete specifications for both products can be found in the
AD5700/AD5700-1 data sheet available from Analog Devices,
Inc., which should be consulted in conjunction with this user
guide when using the evaluation board.

AGND and DGND are connected together on the board to
provide a single GND signal. To power the EVAL -AD5700-1EBZ,
supply 3.3 V between the VCC and GND inputs for the analog
supply of the AD5700/AD5700-1. With L5 inserted (default), this

LINK OPTIONS
L2
A number of links on the evaluation board must be set for the
required operating setup before using the board. The functions
of these link options are described in detail in Table 2. The
default setup is using the on-chip reference, the crystal
oscillator, and the internal receive filter (see Table 1).

The AD5700/AD5700-1 support numerous clocking configurations to allow a simple, low cost solution. The
AD5700/AD5700-1 can use an external crystal or ceramic resonator, a CMOS input, or an internal RC oscillator
(AD5700-1 only). The CLK_CFG0, CLK_CFG1, and XTAL_EN links configure the clock generation as follows:

FILTER_SEL, L1, L2
REF_EN
These link options set whether the internal or external receive band-pass filter is used at the HART input.
Setting FILTER_SEL to Position B and L1 and L2 to Position A sets the board to use the internal receive band-pass filter.
Setting FILTER_SEL to Position A and L1 and L2 to Position B sets the board to use the external receive band-pass filter.
This sets whether the internal or an external reference is used.
Position A—disables the internal reference, and a buffered external 2.5 V reference source must be applied at REF.
Position B—enables the internal 1.5 V reference and buffer.
DUPLEX
Allows the modulator and demodulator of the AD5700/AD5700-1 to be enabled at the same time.
Position A—the AD5700/AD5700-1 operate in half-duplex operation (controlled by RTS).
Position B—the AD5700/AD5700-1 operate in full duplex operation, with the modulator and demodulator of the
AD5700/AD5700-1 enabled at the same time.
L5
Allows VCC to be connected directly to IOVCC
.
Inserted—VCC is connected to IOVCC
.
Not inserted—VCC is disconnected from IOVCC
