51 / 61 page  GS9092A GenLINX® III 270Mb/s Serializer for SDI and DVB-ASI Final Data Sheet 34715 - 5 February 2013 51 of 61 3.13 GSPI Host Interface The GSPI, or Gennum Serial Peripheral Interface, is a 4-wire interface provided to allow the host to enable additional features of the GS9092A and/or to provide additional status information through configuration registers in the device. The GSPI comprises a serial data input signal SDIN, serial data output signal SDOUT, an active low chip select CS, and a burst clock SCLK. Because these pins are shared with the JTAG interface port, an additional control signal pin JTAG/HOST is provided. When JTAG/HOST is LOW, the GSPI interface is enabled. When operating in GSPI mode, the SCLK, SDIN, and CS signals are provided by the application interface. The SDOUT pin is a non-clocked loop-through of SDIN and may be connected to the SDIN of another device, allowing multiple devices to be connected to the GSPI chain. The interface is illustrated in Figure 3-12. Figure 3-12: GSPI Application Interface Connection All read or write access to the GS9092A is initiated and terminated by the host processor. Each access always begins with a 16-bit command word on SDIN indicating the address of the register of interest. This is followed by a 16-bit data word on SDIN in write mode, or a 16-bit data word on SDOUT in read mode. Note: All unused GSPI input pins (CS, SDIN, SCLK) should be pulled up to VCC_IO.
