3 / 17 page ML6427 3 PIN DESCRIPTION PIN NAME FUNCTION 1A/B MUX Logic input pin to select between Bank <A> or <B> of the CV, RGB, or Y/C inputs. Internally pulled high. 2CVINU/Y1 Unfiltered analog composite video or luma video input. Internally pulled high. A composite or luma or green signal must be present on either the CVINFA/Y2 or the CVINFB/ Y3 input to provide necessary sync signals to other channels (R, G, B, Y, C). Otherwise, sync must be provided at SYNCIN. For RGB applications the green channel with sync can be used as an input to this pin (see RGB Applications section). 3CVINFA/Y2 Filtered analog composite video or luma video input for Bank <A>. Note that SYNC is stripped from this signal for the other channels. A composite or luma or green signal must be present on either the CVINFA/Y2 or the CVINFB/Y3 input to provide necessary sync signals to other channels (R, G, B, Y, C). Otherwise, sync must be provided at SYNCIN. For RGB applications the green channel with sync can be used as an input to this pin (see RGB Applications section). 4CVINFB/Y3 Filtered analog composite video or luma video input for Bank <B>. Note that SYNC is stripped from this signal for the other channels. 5 GND Analog ground 6VCC Analog 5V supply 7RINA/Y4 Filtered analog RED video or luma video input for Bank <A> 8RINB / Y5 Filtered analog RED video or luma video input for Bank <B> 9GINA/Y6 Filtered analog GREEN video or luma video input for Bank <A> 10 GINB/Y7 Filtered analog GREEN video or luma video input for Bank <B> 11 BINA/C1 Filtered analog BLUE video or chroma video input for Bank <A> PIN NAME FUNCTION 12 BINB/C2 Filtered analog BLUE video or chroma video input for Bank <B> 13 SWAP CVF Logic input pin to select whether the outputs of CVOUT1/YOUTA and CVOUT2/YOUTB are from filtered or unfiltered CV sources. See Table 1. Internally pulled low. 14 SWAP CVU Logic input pin to select whether the outputs of CVOUT1/YOUTA and CVOUT2/YOUTB are from filtered or unfiltered CV sources. See Table 1. Internally pulled low. 15 BOUT/COUT Analog BLUE video output or chroma output from either BINA/C1 or BINB/C2 16 GOUT/YOUTD Analog GREEN video output or luma output from either GINA/Y6 or GINB/Y7 17 VCCORGB 5V power supply for output buffers of the RGB drivers 18 ROUT/YOUTC Analog RED video output or luma output from either RINA/Y4 or RINB/ Y5 19 GNDO Ground for output buffers 20 CVOUT2/YOUTB Composite video output for channel 2 or luma output. 21 CVOUT1/YOUTA Composite video output for channel 1 or luma output. 22 VCCOCV 5V power supply for output buffers of the CV drivers. 23 SYNCIN Input for an external H-sync logic signal for filtered channels. TTL or CMOS. For normal operation SYNCOUT is connected to SYNCIN. 24 SYNCOUT Logic output for H-sync detect for CVINFA/Y2 or CVINFB/Y3. TTL or CMOS. For normal operation SYNCOUT is connected to SYNCIN. |
