Re: SPDIF ADAU1445/6
SPDIF out sends only two channel, for rest channel You must use external circuit like WM8804, DIT4096 connected to serial out interface of ADAU.

What is the minimum pulse length required on the reset pin to ensure external reset detection by the cortex core on ADuC cortex M3 based products?
View ArticleRe: Minimum pulse on the reset pin
On cortex-M3 based devices with a 16 MHz master clock, such as ADuCM360, ADuCRF101, or ADuCM350, the reset pin should be pulled low for at least 1us to ensure the device interpret this as an external...
