[AKD7756-HF] AKD7756-HF AK7756 Hands Free Evaluation Rev.0 GENERAL DESCRIPTION AKD7756-HF is a Hands-free evaluation kit for the AK7756 which is an audio processor with PCM interface, EEPROM interface, mono voice audio CODEC and microphone pre-amplifier. A speaker amplifier is integrated in this evaluation kit for easy evaluation of Hands-free function by connecting external microphones and speaker units. It is possible to access to the AKD7756-HF via USB interface, and adjustment of voice quality and noise attenuation level can be made with Windows GUI applications. An external Flash Memory for DSP programming is integrated into this kit enabling a stand-alone operation. In addition, an easy connection to a mobile phone is provided by integrated Blue Tooth module for evaluations. ■ Ordering guide AKD7756-HF • AK7756 Hands Free System (HFS) Box • USB Control Adapter • Monitoring Board • AD-DC Converter for main power supply • Control Soft FUNCTION Write/Read access to PRAM, CRAM, OFREG and control registers of AK7756 In/Output Ports: MIC-IN/SPK-OUT/S-AMPOUT/TEL-IN/TEL-OUT Flash Memory (EEPROM) for parameter storage and stand-alone operation Blue-Tooth transceiver Wireless AKD7756-HFS BT-Transceiver Wired AK 2300 AK 7756 Xilinx EEPRO AK7835 Control Box Monitor Board PC <KM101400> 2010/06 -1- [AKD7756-HF] BOARD DIAGRAM ■ Front Panel (1) (2) (3) (4) (5) (6) (7) (8) (9) ■ Rear Panel (10) (11) (12) (13) ■ Main Board (14) (15) <KM101400> (16) 2010/06 -2- [AKD7756-HF] ■ Description No. (1) Name CONTROL PORT (2) (3) MONITOR Reset (push switch) (4) STATUS (LED) (5) FRONT DIP SW (6) DSP MODE (LED + Toggle Switch) JX0/JX1 (push switch) HOOK (push switch) (7) (8) (9) (10) BT – RST (push switch) +12V (power supply) (11) (12) GND Analog interface (13) (14) VCC-OUT SPK_PDN (15) PCB DIP SW1 (16) D_BT_IF port (JP1: 5pin header) Function This port is used when the control code is written to the AK7756 via PC, or when flash memory data is downloaded.

Filter attribute table <KM101400> 2010/06 -8- [AKD7756-HF] 8 bands adjustments can be made in RUN state by GUI. (1) (2) (3) Figure 5. Control S/W [PEQ] tab screen (1) Select [PEQ] tab to open Equalizer dialogue. (2) Push down the [USE] button to write this operation setting to the DSP. Set the initial address of the PEQ band, which need to be modified, to [ADDR]. Set quality factor of the filter to [Q]. Set a cutoff frequency of the filter to [FREQ]. Use the [Type] pull-down menu box to select a filter type. When filter type is “DIP”, the slid bar is available for setting. (3) This function is enabled only when CODEC and DSP buttons are pushed down (CODEC and DSP are in RUN state). <KM101400> 2010/06 -9- [AKD7756-HF] ■ Noise Canceller The noise canceller sets optional noise attenuation for 6 divided voice bands. This noise cancel adjustment is made with the real time NC parameter adjustment function of GUI software as shown in the following diagram. Sensitivity Adjustment When it is high, sensitivity decreases, and stability improves. When it is low, sensitivity improves, and stability decreases. The noise attenuation of each band is adjusted. Unit = [dB] GAIN0= Lowest frequency band GAIN5= Highest frequency band Figure 6. Control S/W [NC Tune] tab screen ■ Parameter Adjustment Set the parameters in CRAM to adjust Hands Free setting. In this instruction manual, CRAM addresses are expressed as C (xx). Address = 4Ch is shown below as an example. Example: C(4Ch) CRAM Address 4Ch A corresponding example to the CRAM file is shown below. Figure 7. AK7756 CRAM File Format Figure 7 shows that 0710h is stored to C(0004Ch) when this file is downloaded. <KM101400> 2010/06 - 10 - [AKD7756-HF] With GUI, it is possible to make adjustment of 8 CRAM parameters simultaneously in RUN state. (1) (2) (3) Figure 8. Control S/W [Mon/Slider] tab screen (1) Select [Mon/Slider] tab. (2) Push down the [USE] button to write this operation setting to the DSP. First, write the address to [ADDR]. Without using the slid bar, it is also possible to input the value to [VAL]. Set the range of the slide bar to [MAX] and [MIN]. (Usually 7FFF ~ 0000) (3) This function is enabled only when CODEC and DSP buttons are pushed down.
