TUSTIN, Calif.--TDK Semiconductor Corp. here announced an expansion of its AVXPro family of audio/video driver ICs with the addition of two new devices that support two or four video channels in addition to four audio channels.
"The initial AVPro devices were developed to address the SCART switching functions required in European applications," explained Tim Jackson, vice president of TDK Semiconductor's Multimedia business unit in Tustin. "By further extending the line into more universal applications, we are positioned to serve a worldwide market in the growing set-top box arena."
The AVPro 5000A is a two-video and four-audio driver IC. It is designed to support two composite video signals and two pairs of right and left audio signals, said TDK. This device is suited for applications such as Web-TV boxes and VCRs where two composite outputs are required, according to the subsidiary of Japan's TDK Corp.
The AVPro 5000B is a four-video and four-audio driver IC. It is designed to support two composite videos, one set of S-Video (Y & C), and two pairs of right and left audio signals. TDK said this chip is aimed at digital set-top boxes and DVD players, which require composite and S-Video outputs.
For these devices, each video driver has a gain of two with output buffer designed to drive a 150-ohm load. Each audio driver is capable of providing a nominal output of 2 Vrms (3.2 Vrms maximum), and the gain of each audio driver is individually set using a pair of external resistors.
The AVPro 5000A device is available in a 20- or 24-lead SOIC package. The 24-lead SOIC package includes the function control output for setting television aspect ratio in some video applications, said TDK. Samples and evaluation boards are now available, with production planned for next month. Pricing for the 5000A is set at $1.10 each in quantities of 10,000 units.
The AVPro 5000B device is available in a 24- or 28-lead SOIC package, which includes the function control output. Samples and evaluation boards for the AVPro 5000B will be available in August. Pricing for the 5000B is $1.30 each in 10,000-unit quantities.
