Asuka Semiconductor Inc. has developed a series of DTV (digital TV) related system modules based on DVB-T SoCs (system-on-a-chips).

The company explains that the core of the SoCs adopts a built-in advanced cofdm demodulator, and supports passive and active antennas. The range of the reception is from 145.1MHz to 862MHz, and the reception capability is from -20dB to -80dBm. In addition, the modules support the selection of 6-/7-/8MHz channel bandwidth.

The new series of Asuka's modules employs 48KHz audio sampling rate to deliver a variety of stereo/mono-left/mono-right modes. These devices support encoding and decoding of the MPEGII data stream to generate video with high quality. The system S/W also provides a user-friendly OSD man-machine interface, added the company. Aside from English and Chinese, other languages are included as well. It allows users to control by the infrared remote control devices or the keyboard. In addition, an RS-232 connection port can be served as the I/O port of S/W upgrade if needed.

The DVB-T modules announced include a TV-STB module and a PC-STB module. The TV-STB module, called Panache, possesses built-in A/V, S-video, YCbCr and YPbPr output terminal interfaces, and measures 12(L)-by-7(W)-by-1.6(H)cm. Meanwhile, the PC-STB module contains a VGA input and a VGA output, which are supposed to be connected to the VGA output and the VGA input of the PC monitor, respectively, to selectively show the digital TV or the computer data on the monitor screen.
