The I9600 is a 9600baud half-duplex serial modem controller suitable for use with wideband receivers, transmitters and transceivers. It takes care of preamble, synchronisation, bit balancing and error checking and enables a transparent radio data link to be established between radio devices.
The Narrow band Evaluation Kit (NBEK) IC can be used as 1200baud half-duplex serial modem suitable for narrow band receivers, transmitters and transceivers (or any RF modules with >5kbps data rate).
