All converted channel results are output on a single LVDS self-clocked serial interface that significantly reduces external hardware.An SPI-compatible serial interface allows configuration of the AFE using SDI input. The SDO output allows the user to daisy chain several AFEs on a single 3-wire bus.
An integrated AFE timing sequencer controls the sampling activity of the analog front end (AFE). The sequencer is programmed via the SPI port and is timed by a single clock, ACLK.
