Serial link and front end interface
The Serial Link (SLINK) and the Front End interface (FEI) blocks have been designed to
connect the STA662 with different kind of tuners such as STA606 or STA610. The SLINK
block performs serial to parallel conversion of data coming from the tuners while the FEI
block performs decimation, filtering and other digital signal processing such as gain control,
DC offset cancellation, image rejection and so on.
The Frontend interface is made up of four processing path: two dedicated to DAB and two to
AM, FM, HD Radio or DRM baseband signal processing. If the system clock is provided by a
frontend tuner then this FE must be connected to interface number 2 or 3.
APB peripherals
Three dedicated peripheral bus (APB0, APB1 and APBC) connect the AMBA architecture to
several interfaces like 5 x SSP, EFT, MTU, I2C, GPIO, 3 x UART and Host interfaces.
System management unit
A system management unit (SMU) has been designed to control all the top level
functionalities. These register are mapped on the APBC bus.
Clock and reset distribution unit
A clock and reset distribution unit (CRDU) is designed to generate and distribute all the
needed clocks and resets. A System PLL and an Audio PLL are part of this logic.
