———-[Mobile IO Conversion]<\/strong>———–<\/p>\n

The MIO series uses Asahi Kasei (AKM) converter chips.<\/p>\n

The AKM 5383<\/a> is a 108 kHz 24-bit ADC, used in both the ULN2<\/a> and 2882<\/a><\/p>\n

The AKM 4393<\/a> is a 96 kHz 24-bit sigma-delta DAC, used in both th2 ULN2<\/a> and 2882<\/a><\/p>\n

The AKM 5394<\/a> is a Multi-Bit 192kHz 24-bit sigma-delta ADC used in the ULN8<\/a><\/p>\n

The AKM 4395<\/a> is a Multi-Bit 192 kHz 24-bit-sigma-delta DAC used in the ULN8<\/a><\/p>\n

These are both stereo chips, so the ULN-2<\/a> has one for input and two for output, while the 2882<\/a> has four of each of them for the main analog I\/O plus an additional DAC for the cans. The ULN8<\/a> has 8 of each, plus a DAC for the cans.<\/p>\n

depending upon the sample rate, these AKM converters run at 128x oversampling – which happens to be the same rate as SACD. The DACs also have an 8x digital filter inside.<\/p>\n

SRC in the 2882<\/a> and ULN-2<\/a> use a Cirrus Logic CS8420<\/a> Digital Audio Sample Rate Converter which runs at 108 kHz and 24-bit for real-time SRC.<\/p>\n

The ULN8<\/a> uses a Cirruc logic CS8406-CZZ<\/a> for AES input\/output at 192kHz<\/p>\n

There is a 24.57 MHz crystal on the Master Board, which matches the AK4393 clock requirement of 24.576 MHz for 48 kHz @ 512x oversampling and 96 kHz at 256x oversampling.<\/p>\n","protected":false},"excerpt":{"rendered":"
