Slots and Sample Formats

BT830 receives and transmits on any selection of the first four slots following each sync pulse. Slot durations are
either 8 or 16 clock cycles:



8 clock cycles for 8-bit sample formats



16 clock cycles for 8-bit, 13-bit, or 16-bit sample formats

BT830 supports:



13-bit linear, 16-bit linear, and 8-bit µ-law or A-law sample formats



A sample rate of 8 ksps



Little or big endian bit order



For 16-bit slots, the three or eight unused bits in each slot are filled with sign extension, padded with zeros or a
programmable 3-bit audio attenuation compatible with some codecs.
