1. General Description
The GigaSTaR
Digital Display Link is a high-speed serial and long distance link for video, audio and digital data, which
supports the popular VESA standard but also proprietary video formats from VGA to UXGA with color depth up to 24 bits.
1.1
Link Interface
The INDT/R165B link requires one single twisted pair cable for the high-speed downlink. The INDT/R330B provides double
bandwidth by using two twisted pairs. Both devices offer an uplink connection using a twisted pair. The downlink must be
established before the uplink can be activated.

Figure 1.1: GigaSTaR Digital Display Link Interfaces
The transmitter’s and receiver’s generic parallel RGB interfaces (CMOS/TTL compatible) support direct connection to the
parallel data port of any graphic controller or to any flat panel display with a parallel pixel data port. The bit width of the
pixel data path can be scaled to support the 18- or 24-bit mode with 1 pixel/clock, the 36- or 48-bit mode with 2 pixel/clock,
or the 12-bit mode with ½ pixel/clock. Pixel data can be clocked into the transmitter on the rising, falling or on both edges
(only 12-, 18-, 24-bit mode) of the pixel clock. Pixel data are provided at the receiver on the rising, falling or on both edges
(only 18-, 24-bit mode) of the pixel clock.
1.1.1
Link Interface Bandwidth
The bandwidth of the downlink is shared between video, audio and sideband data. Disabling audio and/or sideband
channels, even partially, increases the available bandwidth for the video data. The video configuration required for VESA
standard compatible video resolutions is shown in
Table 1.1
and
Table 1.2.

Pixel Interface
General Information
The pixel interface is designed to support direct interfacing to any digital graphics device with a parallel data port such as
graphic-cards/controllers, CCD cameras or flat panel TFT displays. With standard interface devices the data port can also
be adapted to systems with non-generic parallel interfaces such as DVI or LVDS/OpenLDI.

The transmitter’s pixel interface accept pixel data with a pixel clock frequency of 24 – 161 MHz (full pixel mode). In single-
ended mode, PX_CLK+ is the clock input and PX_CLK– has to be tied to GND. All pixel data and pixel clock inputs of the
transmitter can be selected through the V
REF
-pin to either work with conventional graphic controllers with 3.3 V output
voltage swing or to work with latest controllers with low voltage swing (1.0 – 2.0 V, see
Figure 3.3 VREF Reference
Circuitry).
The pixel data and pixel clock outputs of the receiver provide a 3.3 V CMOS compliant output.
1.2.2
Pixel Interface Modes
The pixel interface is configurable to accommodate all the various graphic interface standards in the market. The width of
the pixel interface is a function of the selected operating mode.
•
In
half-pixel mode
the bit width of the pixel interface is
12-bit.
In half-pixel mode the lower and upper 12 bits of a parallel
video interface (24-bit) are transmitted at consecutive sampling edges. This mode is supported only at the Tx devices.
•
In
full-pixel mode
the bit width of the pixel interface can be set to support an
18- or 24-bit
wide parallel video interface.
1 pixel per sampling edge is transmitted.
•
In
double-pixel mode
the bit width of the pixel interface can be set to support a
36- or 48-bit
wide parallel video
interface. 2 pixels per sampling edge are transmitted.
1.2.3
Pixel Clock Sampling Modes
The pixel interface can be set to support data sampling at the
rising, falling
or at
both edges
of the pixel clock,
depending on the selected mode.
Table 1.4
and
Figure 1.3, Figure 1.4, Figure 1.5
summarize the various options for configuring the pixel interface.
