- 34 -IC GM5221 PQFP-208 (Analog Input Port)Pin No. Pin Name Description
141 AVDD_BLUE_3.3Analog power (3.3V) for the blue channel. Must be bypassed with
capacitor to AGND_BLUE pin on system board.
142 BLUE+ Positive analog input for Blue channel.
143 BLUE- Negative analog input for Blue channel.
144 AGND_BLUE Analog ground for the blue channel. Must be directly connected to the
analog system ground plane.
145 AVDD_GREEN_3.3 Analog power (3.3V) for the green channel. Must be bypassed with
capacitor to AGND_GREEN pin on system board.
146 SOG_MCSS Dedicated Sync-on-Green pin.
NOTE: This pin requires the same AC-couple capacitor (if applicable)
like the regular RGB input pins.
147 GREEN+ Positive analog input for Green channel.
148 GREEN- Negative analog input for Green channel.
NOTE: For SOG support this pin should be pulled down to GND
through a 1M
Ω
, resistor.
149 AGND_GREEN Analog ground for the green channel. Must be directly connected to the
analog system ground plane.
150 AVDD_RED_3.3 Analog power (3.3V) for the red channel. Must be bypassed with
capacitor to AGND_RED pin on system board.
151 RED+ Positive analog input for Red channel.
152 RED- Negative analog input for Red channel.
153 AGND_RED Analog ground for the red channel. Must be directly connected to the
analog system ground plane.
154 AVDD_ADC_3.3 Analog power (3.3V) for ADC Analog blocks that are shared by all three
channels. Includes bandgap reference, master biasing and full scale
adjust. Must be bypassed with capacitor th AGND_ADC pin on system
board.
156 AGND_ADC Analog ground for ADC analog blocks that are shared by all three
channels. Includes bandgap reference, master biasing and full scale
adjust. Must be directly connected to analog system ground plane.
163 GND1_ADC Digital GND for ADC clocking circuit. Must be directly connected to the
digital system ground plane.
164 VDD1_ADC_1.8 Digital power (1.8V) for ADC encoding logic. Must be bypassed with
capacitor to GND1_ADC pin on system board.
