Link Transmitter & Receiver
The GigaSTaR
Digital Display Link 166/331-series is an
innovative high-speed link featuring simultaneous
transmission of digital video, audio and bi-directional
sideband data over one standard shielded twisted pair
cable up to 50 m (500 m with fiber optics). It supports
VGA…UXGA as well as Digital TV (DTV) and High-
Definition TV (HDTV) formats up to 720p or HDTV1080i
with up to 16.7 million colors. The sideband channels
provide bandwidth up to 264 Mbps to connect peripheral
components like keyboard, mouse, disc drive and audio
devices.
Compared to the 165/330-series the 166/331 offer
additional features like a tristate pixel interface (Rx only)
and an integrated pixel buffer to reducing pixel clock
variations. The 166/331 may be used as direct drop-in
replacement for the 165/330 under specified conditions.

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 and Digital TV standards as well as proprietary video formats from VGA to UXGA with color
depth up to 24 bits.
1.1
Link Interface
The INDT/R166B link requires one single twisted pair cable for the high-speed downlink. The INDT/R331B 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.

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.
Pixel data can be clocked into the transmitter on the rising, falling or on both edges (18-, 24-bit mode) of the pixel clock.
Pixel data are provided at the receiver on the rising, falling or on both edges (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
or Digital TV (DTV) / High-Definition TV (HDTV) standard compatible video resolutions is shown in
Table 1.1
and

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.

INDT/R331B
The transmitter’s pixel interface accepts pixel data with a pixel clock frequency of 24 – 161 MHz (full pixel mode). For the
Tx side in single-ended mode, PX_CLK+ is the clock input and PX_CLK– has to be tied to GND. A differential pixel clcok
mode on the Rx side is not available. 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
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 1.4, Figure 1.5
summarize the various options for configuring the pixel interface.
