SNLS477B October 2014 – November 2018 DS90UB948-Q1
This deserializer features six I2S output pins that, when paired with a compatible serializer, support surround-sound audio applications. The bit clock (I2S_CLK) supports frequencies between 1 MHz and the smaller of < PCLK/2 or < 13 MHz. Four I2S data outputs carry two channels of I2S-formatted digital audio each, with each channel delineated by the word select (I2C_WC) input.
When paired with a DS90UB925Q, the deserializer I2S interface supports a single I2S data output through I2S_DA (24-bit video mode) or two I2S data outputs through I2S_DA and I2S_DB (18-bit video mode).
