Power is supplied to the delay line circuit in the surround block from VCC2 (pin22)and GND2 (pin41), and power is supplied to the digital circuit blocks from VDD (pin45) and VSS (pin50). * One Point that requires care is that mutual interactions (due to, for example, common impedances) between these power supply lines may influences the signals being processed, if this happens, phenomena such as souns not being moved smoothly may occur. * To prevent such phenomena from occurring, observe the following recommendations. - Design the printed circuit board layout so that all VCC and ground lines are as short and as wide as possible. - Connect all VCC and ground lines to the power supply independently. - Connect capacitors (about 220F) between each of the VCC and ground pairs as close to the IC pins as possible. Note : A sample power supply line layout is presented in the above diagram for reference. No.6628-4/14 47 pF + C C B B C C C C B A D B B B B A A D A A A D D D D R L |
