M65677FP
DIGITAL NTSC/PAL ENCODER
DESCRIPTION
The M65677FP encodes CCIR601 or CCIR656 format Y/Cb/Cr data
into analog NTSC and PAL video signals, including Digital Signal
Processing functions such as Closed Caption encoding, Overlay
OSD, Anti Video Copy Processing (Note1) e.t.c. It also includes
peripheral processing function such as 10bit DAC e.t.c., so that low
cost and compact system can be realized.
FEATURES
• Macrovision’s video anti copy process
Rev 7.01 supported (Note1)
• Overlay CGMS signal on line 20/283 for 525/60 (Note3)
• Generate CRCC for CGMS Signal
• Overlay WSS signal on line 23 for 625/50 (Note4)
• Color adjustment (TINT/color control)
• NTSC, B/G PAL or MPAL Video Outputs
• Component Y/C Video (S-Video) and CVBS or Y/U/V Outputs
• Supporting CCIR601 and CCIR656 format data
• Closed Caption Manager on line 21/284 for NTSC
• Generate ODD parity for Closed Caption Manager
• H/V Sync and Composite generating
• Overlay Digital OSD Supporting Y/Cb/Cr 4:4:4
• Over sampling Filter
• 2ch 10bit DAC and 3ch 6dB Amp (Note2)
• 3.3V I/O interface
• I2C Bus Interface for Controls
• Power down mode

44 AVDD1
Supply Analog supply for DACs.
45 AVSS1
Supply Analog ground for DACs.
46 DAY
Luma or U signal output.
O It should be connected to the analog supply via a load resistor (RL).
The output amplitude is set up by reference resistor (Rref) and RL.
47 Cref
I
A reference current source for chroma or V signal output DAC.
It should be connected to the analog supply via a reference resistor (Rref).
48 Yref
I
A reference current source for Y or U DAC.
It should be connected to the analog supply via a reference resistor (Rref).
49 Ycomp
I
Phase compensation for Y or U DAC.
It should be connected to the analog ground via a capacitor.
50 N.C.
No connection.
51 DVDD1
Supply Digital supply for the internal logic.
52 DVSS1
Supply Digital ground for the internal logic.
53 Xout
O
System clock output.
It must be in no connection except for a connection to a X'tal oscillator.
54 Xin
