Analog Devices Inc. ADMV8526-EVALZ Evaluation Board facilitates the evaluation of the ADMV8526 digitally tunable band-pass filter (BPF). The ADMV8526 features a 1.25GHz to 2.60GHz adjustable FCENTER frequency range and uses an 8-bit value (256 states), integrating a patent-pending interpolation technique.
The ADI ADMV8526-EVALZ Board combines the ADMV8526 chip, a negative voltage generator, low dropout (LDO) regulators, and an interface to the EVAL-SDP-CS1Z (SDP-S) system demonstration platform (SDP) enabling a simple and efficient evaluation. Furthermore, the negative voltage generator and LDO regulators permit the ADMV8526 to be powered by either the 5V USB supply voltage from the PC via the SDP-S or by using two external power supplies.
The ADMV8526 chip can be programmed using a 4-wire serial peripheral interface (SPI), and the SDP-S controller allows interfacing with the SPI of the ADMV8526 through the Analysis Control Evaluation (ACE) software.
