| SiI 1172 | PanelLink Transmitter The SiI 1172 is the world's first single-link TMDSTM transmitter to break the bandwidth barrier and support an amazing 225 MHz bandwidth. The latest addition to SiI's comprehensive SiI 1000 family of DVI solutions, the SiI 1172 transmitter incorporates next-generation PanelLink(R) technology to support bandwidths of 25 to 225 MHz. As a result, the SiI 1172 supports LCD monitors and projectors with resolutions that range from VGA to QXGA (2048 x 1536). Three TMDS data channels for RGB send data at up to 2.25 Gbps per channel. The SiI 1172 incorporates an industry-standard 12-bit (1/2 pixel per clock edge) interface for true color (16.7 million) support. Built-in flexibility enables customers to use pins to configure settings or the I 2C interface to program registers. The SiI 1172 is available in a low-cost, easier-to-use, 48-pin TSSOP package with a 57 % smaller footprint compared to other discrete DVI transmitters. By incorporating the most advanced PanelLink DVI technology available today, the SiI 1172 transmitter brings higher performance and guaranteed compatibility to single-link DV I applications while enabling faster time to market, smaller form factor designs and lower system costs. DVI-compliant Quality The DVI 1.0 specification defines the precise system-level signaling at the output of a DVI transmitter system and at the input of a DVI receiver system. As a result, any DVI-compliant host will always interoperate with any DVI-compliant display. The most comprehensive method to determine the quality and compliance of a DVI transmitter is to measure the TMDS "eye" diagram as defined by the DVI 1.0 specification and the DVI Test & Measurement Guide. Only high-performance PanelLink DVI transmitters, such as the SiI 1172, yield consistently robust differential signal "eyes" that exceed the minimum "eye" width & height requirements of the DVI specification throughout the full DVI bandwidth of 25-165 MHz. At bandwidths above 165 MHz, the SiI 1172 is interoperable with PanelLink receivers also rated to run over 165 MHz.
