3.11 Parallel Data Outputs

Data outputs leave the device on the rising edge of PCLK as shown in Figure 3-7.

The data may be scrambled or unscrambled, framed or unframed, and may be

presented in 10-bit or 20-bit format. The output data bus width is controlled

independently from the internal data bus width by the 20bit/10bit input pin.

Likewise, the output data format is defined by the setting of the external

SMPTE_BYPASS and DVB_ASI pins. Recall that these pins are set by the

application layer as inputs to the device.

3.11.1 Parallel Data Bus Buffers

The parallel data outputs of the GS9060 are driven by high-impedance buffers

which support both LVTTL and LVCMOS levels. These buffers use a separate

power supply of +3.3V DC supplied via the IO_VDD and IO_GND pins.

All output buffers, including the PCLK output, may be driven to a high-impedance

state if the RESET_TRST signal is asserted LOW.
