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.
