Core trio boosts SoC platform
Oki Electric has enhanced its uPLAT series of integrated platforms, which lower development times of SoC LSIs, with the introduction of three core products.
More power from laser modules for WDM systems
Oki Electric has developed a trio of high-power 1480nm pump laser diode modules for WDM (wavelength division multiplexing) optical transmission.
Volume shipments start from January 2005, aiming to achieve production of 500,000 units per month designated for the worldwide market in the fiscal year ending March 2006.
"Though HDD mounted portable audio players have been attracting attention recently, slow transfer speeds from PC to player and short battery life have been some issues", said Akira Kamo, President of Silicon Solutions Company at Oki Electric.
"Oki's system LSIs enable greatly increased speed and performance, small size, and low power consumption, in order to meet the user needs".
"With the total solution Oki provides with its chip and software, HDD audio player manufactures can develop a compact and high performance player in a short timeframe".
The ML696500 series is an LSI intended for HDD audio players.
It enables MP3 and WMA audio files to be played, as well as high-speed data transfer between PC and the player's hard drive.
It comes in two models: the ML69Q6500 with 512Kbyte of Flash ROM; and the ML696500 with no Flash memory.
As both models have onboard USB 2.0 high-speed device controllers and Ultra DMA 66-compatible ATA/IDE controllers, a dramatic increase in data transfer speed between PC and player can be realised, with an effective data transfer rate of 128Mbit/s, compared with 8Mbit/s for USB 1.1 full-speed controllers.
Furthermore, the ML696500 series has simplified the design of complex analogue circuitry by combining primary audio-player component functions onto a single chip.
Previously, components such as the D/A convertor, mounted with a headphone amplifier, A/D convertor mounted with a microphone amplifier required several chips.
Concurrently with the introduction of the ML696500 series, Oki will begin selling SDKs (software development kits) for this LSI, for use in developing software for reproduction of music files, managing hard drive files, and other purposes.
