5V tolerant connection to allow use of 5V Tuner devices
Multiplex setup with COFDM Register Bit 0 = '1'
Multiplex setup with CICSEL3 Register Bits 9:11 = '111'
Multiplex setup with CICSEL3 Register Bit 6 = '1', and GPIS2 Register Bits 24:25 = '01'
Multiplex setup with COFDM Register Bit 0 = '0'
External pull-up to Tuner Vdd PSU required on GPPx lines.
The ADC_IN [0:9] and EXT_IN [0:9] inputs on the Front End interface are configured as “Big Endian”. This means that bit [0]
is the Most Significant Bit (MSB) for the multiplexed functions mapped to that pin.
When the ADC_IN [0:9] and EXT_IN [0:9] pins are used to provide various alternative inputs within one application, then each
set of inputs must have a tri-state buffer. The enables for these buffers should then be controlled by general purpose I/O pins.
Note 8:
6.3 Video DAC Outputs
Note 1:
Video outputs capable of driving between 37.5ohm and 75ohm loads.
