Texas Instruments TVP5147M1PFP manual Output Formatter 1 Register, Output Formatter 2 Register

Functional Description

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).

2.11.28 Output Formatter 2 Register

Subaddress	34h
Default	00h
7	6	5	4	3	2	1	0
	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.
