THS8083A Terminal Functions Order (Continued)
TERMINAL
I/O/B
TYPE
DESCRIPTION
NAME
NO.
I/O/B
TYPE
DESCRIPTION
CLOCK I/O
XTL1_MCLK
20
I
A
Master crystal connection 1 (connects 14.318-MHz crystal) or master clock input (at
14.318 MHz)
XTL2
22
O
A
Master crystal connection 2 (connects 14.318-MHz crystal)
DATACLK1
54
O
D
1st clock output: DATACLK1
The rising edge of this clock can be used by an external device to clock in THS8083A output
data in all modes (see output timing diagrams in Section 4 for more details).
ADCCLK2
53
O
D
2nd clock output: ADCCLK
This clock output is equal to the clock of the ADC converter, optionally inverted and/or
divided-by-2.
DTOCLK3
52
O
D
3rd clock output: DTOCLK.
This clock output is the output of the DTO.
EXT_ADCCLK
56
I
D
External clock input for A/D channels, at pixel clock frequency
ANALOG SIGNAL I/O
CH1_IN
81
I
A
Analog input channel 1. Since this channel includes the composite sync slicer and is not
downsampled in 4:2:2 mode, this channel should be used for green or luminance input, if any
of these features are used.
CH2_IN
88
I
A
Analog input channel 2. In YUV 4:2:2 sampling mode, Pb should be connected to this input to
generate a ITU.BT-601 style output.
CH3_IN
95
I
A
Analog input channel 3. In YUV 4:2:2 sampling mode, Pr should be connected to this input to
generate a ITU.BT-601 style output.
VREFBO_CH1
82
B
A
Reference voltage bottom output channel 1. In normal operation: output. For a specific
configuration, this terminal becomes an input terminal (see Powerdown section in Functional
Description).
VREFTO_CH1
83
B
A
Reference voltage top output channel 1. In normal operation it is an output. For a specific
configuration, this terminal becomes an input terminal (see Powerdown section in Functional
Description).
VREFBO_CH2
89
B
A
Reference voltage bottom output channel 2. See VREFBO_CH1.
VREFTO_CH2
90
B
A
Reference voltage top output channel 2. See VREFTO_CH1.
VREFBO_CH3
96
B
A
Reference voltage bottom output channel 3. See VREFBO_CH1.
VREFTO_CH3
97
B
A
Reference voltage top output channel 3. See VREFTO_CH1.
VMID
73
B
A
Midlevel input range (input common mode). In normal operation it is an output. For a specific
configuration, this terminal becomes an input terminal (see Powerdown section in Functional
Description).
