1.0 SDM-875p HDTV Serial Digital to Component VGA/DVI Converter

1.1 Introduction

The SDM-875p is a High Definition digital converter converting

serial digital HDTV (SMPTE 292M) to High Definition Component

Analog/Digital (Y/Pb/Pr and RGB). The SDM-875p provides auto-

matic input scan rate detection and supports a wide variety of

input formats including 525i, 625i, 720p, 1080i and 1080p. Output

formats are compliant to EIA/CEA-861-B standard. The primary

application is to convert HD serial to Component Analog/Digital

for the purposes of feeding an HDTV monitor, computer monitor

and projector. (CRT, LCD, Plasma, DLP, D-ILA etc). In order to

support the emerging popularity of 24p equipment and digital dis-

play, the SDM-875p provides VGA and DVI output with selectable

3:2 sequence insertion.

2.0 Overall View

Figure 2 illustrates the SDM-875p's major parts and their loca-

tions. A high-definition or standard definition digital video source

is connected to the HD/SD SDI IN BNC and the Component

Analog/Digital output is provided by the DVI-I connector. Error

status is provided by the status LED. Finally, the power source is

connected to the lockable power connector.

3.0 Installation

3.1 Power Supply

The power supplies LKS-WSU, for 110 V and 220 V operation, is

used to power the SDM-875p. The power supply provides a re-

gulated +5 [email protected] A power source. The SDM-875p employs

a mini XLR-3 connector for its power needs. Figure 3 provides a

detailed pinout of the male connector.

3.2 HD/SD Serial Digital Video Input with Active Loop-

Through

Connect a high-definition or standard definition digital video sig-

nal to the BNC labeled HD-SDI IN. The high-definition serial dig-

ital input signal must conform to the SMPTE 292M standard.

The standard definition serial digital input signal must conform to

the SMPTE 259M-C standard.

Make sure that the input signal cable has a maximum length of

75m (250’) and that all serial digital video equipment are con-

nected point-to-point. For instance, there must be a point-to-

point connection between the HD/SD SDI IN BNC and the source

equipment. If a T-connector is used to connect other equipment,

the maximum specified cable length is no longer valid.

3.3 High Definition Component Analog/Digital Video Output

The high definition component analog/digital video output signal

(Y/Pb/Pr and RGB) is provided by the DVI-I (female) labeled

OUTPUT. A DVI-to-VGA adapter is supplied for analog output.

The output format is automatically selected according to the input

signal; for a complete list of the output formats and related

SMPTE standards refer to section 5 Specifications.

Test Pattern Selection

On: Set the “Test” slide switch to this position to enable

the test pattern on output. The test pattern consists

of a HDTV color bars.

Off: The test pattern is disabled.

Note: in order to output a test pattern, a valid input signal must

be installed.

Markers 4:3 Selection:

On: Set the “Markers 4:3” slide switch to this position to

display 4:3 markers on the 16:9 image.

Off: The 4:3 markers are disabled.

Input format

I: Set the “Input Format” slide switch to this position

for most input signal.

PsF: Set the “Input Format” slide switch to this position

to access additional output format when input format

is 1920x1080 25PsF.

Output format

GBR: For GBR CAV output, set the slide switch to this posi-

tion.

YPbPr: For Y/Pb/Pr CAV output, set the slide switch to this

position.

CS (Composite Sync) on CAV

All: Set the slide switch to this position to add sync to the

color components of the signal. Composite sync is

bi-level for GBR output and tri-level for YPbPr

output.

None: Set the slide switch to this position to output separate

H and V sync.
