AFE Interface
The INT5130 provides a simple parallel interface to the analog front end (AFE). The analog data is clocked into
or out of the INT5130 on a 10-bit bi-directional parallel data bus under control of transmit or receive enable
signals and sample clock references provided to the AFE from the INT5130. The INT5130 also provides a
parallel byte-wide automatic gain control interface.

ADC/DAC Interface
The INT5130 outputs a sequential stream of digital time samples of the OFDM waveforms for transmission.
The digital transmit signal is passed on to the INT1000 Integrated Converter. The INT1000 consists of a
10-bit ADC and 10-bit DAC on a multiplexed 10-bit bi-directional data bus. The ADC digitizes the analog
OFDM receive signal for input to the INT5130. The DAC converts digital samples into analog waveforms.
