rates up to 115.2 kbps. An IrDA SIR protocol encoder/decoder
can be optionally switched into the RX/TX signals to/from
UART 1 to enable these signals to drive an infrared
communication interface directly.
Digital Audio Interface (DAI)
The EP7309 integrates an interface to enable a direct
connection to many low cost, low power, high quality audio
converters. In particular, the DAI can directly interface with
the Crystal
Crystal
feature digital bass and treble boost, digital volume control and
compressor-limiter functions.
CODEC Interface
The EP7309 includes an interface to telephony-type CODECs
for easy integration into voice-over-IP and other voice
