2. General Description
The G21A21 is a high quality SoC, “system on chip” that can produce the effects of reverb, vibrato, chorus,
flanger, echo, tremolo, distortion with stereo 4-band equalizer.
G21A21 was integrated 256Kbytes for delay and support for 16/18/20/22/24bit CODEC I/F.
It can be need minimum external component.
At G21A21 input port, SPI interface are designed to provide input from external MICOM.
G21A21 was integrated real-time power management algorithm for low power consumption.
As a result, G21A21 can operate very long time in battery application.
For the real time control of parameter, G21A21 was integrated click-noise remover.
At audio charateristics, 105dB of SNR get it is used 48Khz sampling rate.
And it can be support Max 96Khz sampling rate.
G21A21 is the best solution all of effectors, such as stomp box, car audio, PA instrument,
karaoke AMP, all kind of effector of bettery operation and high quality sound.
