Functional Description
41 SLES140A—March 2007 TVP5147M1PFP
2.11.27 Output Formatter 1 Register
Subaddress 33h
Default 40h
7 6 5 4 3 2 1 0
Reserved YCbCr code range CbCr code Reserved Output format [2:0]
YCbCr output code range:
0 = ITU-R BT.601 coding range (Y ranges from 64 to 940. Cb and Cr range from 64 to 960.)
1 = Extended coding range (Y, Cb, and Cr range from 4 to 1016.) (default)
CbCr code format:
0 = Offset binary code (2s complement + 512) (default)
1 = Straight binary code (2s complement)
Output format [2:0]:
000 = 10-bit 4:2:2 (pixel x 2 rate) with embedded syncs (ITU-R BT.656) (default)
001 = 20-bit 4:2:2 (pixel rate) with separate syncs
010 = Reserved
011 = 10-bit 4:2:2 with separate syncs
100−111= Reserved
NOTE: 10-bit mode is also used for the raw VBI output mode when bit 4 (VBI raw) in the
luminance processing control 1 register at subaddress 06h is set (see Section 2.11.7).

Reserved Data enable Black Screen [1:0] CLK polarity Clock enable
Data enable: Y[9:0] AND C[9:0] output enable
0 = Y[9:0] and C[9:0] high impedance (default)
1 = Y [9:0] and C[9:0] active
Black Screen [1:0]:
00 = Normal operation (default)
01 = Black screen out when TVP5147M1 detects lost lock (using with tuner input but not with VCR)
10 = Black screen out
11 = Black screen out
CLK polarity:
0 = Data clocked out on the falling edge of DATACLK (default)
1 = Data clocked out on the rising edge of DATACLK
Clock enable:
0 = DATACLK outputs are high-impedance (default).
1 = DATACLK outputs are enabled.
