Description
Test mode select provides the logic levels needed to change the TAP controller from
state to state during the boundary scan test.
Test reset is used to reset the TAP controller (active LOW). Grounding is mandatory
in Functional mode.
Test clock is used to drive the TAP controller.
Test data input is the serial data input for the test data instruction.
Test data output is the serial test data output pin. The data is provided on the falling
edge of TCK.
IF positive analog input for internal ADC
IF negative analog input for internal ADC
positive analog current output of the video output
negative analog current output of the video output
positive analog current output of the SSIF/mono sound output
negative analog current output of the SSIF/mono sound output
External bias setting of the DACs. An external resistor (1 kΩ typical) has to be
connected between RSET and the analog ground of the board. This resistor
generates the current into the DACs and also defines the full scale output current.
The total parasitic capacitance seen externally from the RSET pin has to be lower
than 20 pF.
DAC1 (video DAC) and DAC reference module analog supply voltage (3.3 V typical)
DAC2 (sound DAC) analog supply voltage (3.3 V typical)
DAC reference module analog ground supply voltage (0 V typical)
IF ADC analog supply voltage (1.2 V typical)
ADC analog ground supply voltage (0 V typical)
ADC, PLL and DACs digital supply voltage (1.2 V typical)
ADC, PLL and DACs digital ground supply voltage (0 V typical)
crystal oscillator and clock PLL analog supply voltage (1.2 V typical)
crystal oscillator and clock PLL analog ground supply voltage (0 V typical)
core digital supply voltage (1.2 V typical)
core digital ground supply voltage (0 V typical)
ring digital supply voltage (3.3 V typical)
ring digital ground supply voltage (0 V typical)
internally connected; connect to ground
not connected
