详细描述

SPN1001 FV-1芯片是单个IC中的完整混响解决方案。

通过集成立体声ADC和DAC，SPN1001 FV-1可以像产品信号路径中的任何其他模拟组件一样对待。

SPN1001 FV-1总共可以访问16个程序，其中8个内置在内部ROM中，设计人员可以选择将串行EEPROM与8个附加程序连接起来。通过使用外部EEPROM，设计人员可以创建自定义程序集，而无需系统中的微处理器。

通过3个电位计输入，程序可能具有实时可变参数，例如混响中的衰减时间、合唱中的速率和深度或滤波器中的频率。这些输入可用作程序的系数，并且可以彼此独立使用。

DSP模块丰富的指令集允许用户对各种效果进行编程。使用LOG和EXP等指令，用户可以轻松编写音频扩展和压缩程序。集成的数字LFO和斜坡发生器允许对合唱、法兰和音高转换进行编程。

The Spin Semiconductor FV-1 chip is a complete reverb solution in a single IC.

With integrated stereo ADC and DACs, the FV-1 can be treated like any other analog component in your products signal path.

The FV-1 can access a total of 16 programs, 8 are built in to the internal ROM and the designer may elect to connect a serial EEPROM with 8 additional programs. By using an external EEPROM, the designer can create a custom program set without the need for a microprocessor in the system.

With 3 potentiometer inputs, programs may have real time variable parameters such as decay time in a reverb, rate and depth in a chorus or frequency in a filter. These inputs are available as coefficients to your program and may be used independently of each other.

The DSP module's rich instruction set allows users to program effects of all kinds. With instructions like LOG and EXP, users can easily program audio expansion and compression routines. Integrated digital LFOs and ramp generators allow for programming chorus, flange and pitch shift.

A FV-1 Demonstration Board is available for the multi effects unit - please see SPN1001-DEVB.
