- Supports IF input
- SPI port interface
- Can be tailored to customer needs
Functional Description
This design is a Mobile WiMAX baseband transceiver core for Mobile station, supplied as a portable and synthesizable Verilog-2001 IP. The system was designed to be used in conjunction with a standard RF tuner. The operation of the transceiver is automated by a master finite state machine.
The transmitter block diagram is shown in Figure 1. The design interfaces to an external Digital to Analog converter (DAC), which transmits the analog signal to the external tuner.
The receiver block diagram is shown in Figure 2. The design interfaces to an external Analog to Digital converter (ADC), which receives the analog signal from the external tuner.
