BANGALORE: Texas Instruments (India) Ltd. (TI) has launched

"Damini" a family of seven receiver integrated circuits (ICs) from the

mixed signal products group. The Damini family of devices, support the emerging

Digital Visual Interface (DVI) standard for high-speed interfaces to

high-resolution digital displays.

This enables digital solutions for desktop LCD monitors, digital CRT monitors

and digital projectors. Damini receiver chips are part of the Panelbus family of

end-to-end DVI solutions from TI Inc, which also includes several transmitter

chips. "Damini the latest in high speed digital interface receiver chips

was architected and developed entirely in India by the Mixed Signal Products

team at the TI facility in Bangalore," said TI India managing director

Srini Rajam.

Damini receivers provide a selection of frequencies (25 - 165 MHz) for

flexible support of display resolutions from VGA (640x480) up to UXGA

(1600x1200) pixels. These products emulate DVI 1.0 compliance, offering features

that enable designers greater versatility to implement new display standards. In

addition, TI leverages its DSP and analog technologies to enhance image quality.

The new TFP401, TFP201 and TFP101 DVI receivers provide a range of speeds for

design flexibility 165MHz, 112Mhz and 86MHz respectively. These devices support

single and dual pixel/clock output modes. High skew tolerance keeps reception

quality high. In addition, while competitor devices use only three times

over-sampling, TI incorporates four times over-sampling for better performance.

Alternate versions of TFP401A, TFP201A and TFP101A receivers contain

additional circuitry that allows the TI devices to interface to non-compliant

transmitters that output undesirable jitter. All these Damini receivers are pin

compatible with competitive receivers. TI has chosen a single pin-out for

flexible step-up and step-down speed choices at build time, based on customer

requirements. Though OEMs till date had to use multiple circuit-board designs

for each speed grade TI's new pin-compatible solutions will change that.
