INDT/R330B
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.
