AD6623 EVALUATION PCB AND SOFTWARE
Analog Devices offers a fully populated printed circuit board and
necessary software to evaluate the AD6623 performance. The
software loads the AD6623 program registers, loads RCF (RAM
Coefficient Filter) coefficients and programs the onboard FPGA
and microcontroller. Designers should contact their local Analog
Devices product distributor for ordering information.
The PCB and software have been designed for maximum
flexibility to accommodate many different applications with
minimum need of external devices. Please refer to the AD6623
Evaluation Board Manual for detailed information.
FIR filter design is an extremely important consideration in UMTS
(Universal Mobile Telecommunications System), wideband
CDMA and other sophisticated data transmission schemes. Trans-
mitted signals must comply with channel specifications to assure
non-interference with neighboring signal channels as well as
minimizing inter-symbol interference. The AD6623 FIR filter
software was designed to fulfill these goals. The latest AD6623
evaluation board and FIR filter software are both available from
the Analog Devices web site at http://www.analog.com/
Additional features of the AD6623 PCB kit:
Onboard 14-bit, 175 MSPS Interpolating TxDAC
(AD9772A) for analog reconstruction of digital outputs.
(Appropriate external anti-alias filter may be required.)
On board voltage regulation requires only a single 9 V, 1 Amp
external power supply to power all devices with 2.5 V, 3.3 V
and 5 V.
Digital outputs can be cascaded to a second AD6623 PCB for
up to 8 output channels from a single DAC.
Onboard “can type” crystal clock or BNC for external single-
ended clock oscillator. CLK buffers are provided for every
driven device
AD6623 software utilizes the serial port of a Personal Computer for
board programming—supports Windows
95, 98, NT and 2000.
High quality, multi-layer PCB
Comprehensive instruction manual complete with schematics,
parts layout diagrams, illustrations.
