Irvine, CA, August 27, 2001 – Toshiba America Electronic Components Inc. (TAEC) has expanded its lineup of Toslink modules with the introduction of new transmitting and receiving devices. The new modules use optical interconnects to achieve isolation and noise-free operation, enabling clear transmission of the audio signal. According to Toshiba management, the devices also offer the industry's highest rates of transmission to enable Dolby Digital Surround Sound and Sony DTS in a variety of applications including set-top boxes, DVD players, desktop and portable computers, digital television, mini-disc players, audio and video receivers, game consoles, and digital tuners.

“Audio quality for consumer electronic devices has greatly improved over the past several years due to the advent of digital satellite systems and digital cable, however consumers are still demanding better quality audio solutions,” said Brach Cox, business development manager, Optoelectronics Devices for TAEC. “With the introduction of the Toslink optical transmitting and receiving solutions, we are responding to those customer requirements to create a higher quality audio solution for the consumer electronics marketplace.”

Technical Features

The TOTX141/TOTX141P and TOTX179/TOTX179P transmitting devices, and the TORX141/TORX141P and TORX179/TORX179P receiving devices are available in standard panel mount and mini-mount modules. The new TOTX179S and TORX179S transmitting and receiving devices are available in the middle mount package module.

The TOTX141/TOTX141P transmitter offers a data rate of direct current (DC) to 15 Mbit/s NRZ. This enables up to 5.1 channels of clear digital audio &$8211; specs required for Dolby Digital Surround Sound, Sony DTS and other high-definition audio transmission formats. In addition, the TOTX141/TOTX141P transmitter offers a nominal supply voltage of 3.0 V. The TORX141/TORX141P receiving module is highly sensitive and has a data rate of 0.1 to 15 Mbit/s with a nominal supply voltage of 3.0 V. The minimum receivable power for the receiver is -27 dBm.

The firm's TOTX179/TOTX179P and TOTX179S transmitters have a high data rate of DC to 12.8 Mbit/s, which the firm claims surpasses most competitive solutions in the marketplace, in addition to supporting Dolby Digital Surround Sound. Like TOTX179 transmitters, the TORX179/TORX179P and TORX179S receiving modules have data rates ranging from 0.1 to 12.8 Mbit/s.
