June 20, Tokyo – Oki Electric Industry Co., Ltd. (hereinafter referred to as OKI) began to supply Sony vgp bps2c the most suitable for recording and playback for portable devices the world’s smallest 16-bit audio CODEC chip, “ML2612 Series” sample.
The chip uses OKI’s W-CSP (Note 1) technology enables the world’s smallest 2.0mm × 2.5mm package size. Even small degrees of freedom for the design of small portable devices, you can also configure the microphone near the audio CODEC, and thus the VGP-BPS8 decline in sound quality caused by external noise control minimum. Moreover, the chip has built-in recording can be removed when the system noise, wind noise and other audio filters, as well as be able to compensate for the audio playback device when the inherent frequency response characteristics of small-scale equalizer.
OKI plans to begin in September 2007 with production quantities available in the chip.
In general, for devices with a microphone to the microphone of the weak perfect digital output signals, often must be installed near the microphone audio CODEC chip. A result, the design of the microphone around the freedom will be restricted. More recently, a film with a digital camera, can confirm VGP-BPS2A pronunciation learning machine with a microphone portable devices continue to emerge. Moreover, these devices smaller and thinner requirements are growing at an unprecedented rate, therefore, subject to limited installation space, audio CODEC chip and become the noise sources and other components installed on the same piece of circuit boards, high-density installation of Necessity is also becoming increasingly apparent.
OKI Group with VGP-BPS10
Silicon Solutions Company Masahiko Morioka, President said: “The response to these needs, OKI developed the equipment necessary to make a portable microphone amplifier, A / D converter (hereinafter referred to as ADC), D / A converter (hereinafter referred to as DAC), speaker amplifier to achieve ultra-small package, the audio CODEC. especially the W-CSP package can achieve in the past for small audio CODEC chip, 1 / 3 of the following package size, a significant improvement in the design of freedom around the microphone. but also through the built-in you can remove the recording of wind noise and the single-frequency sound system noise programmable filters, as well as be able to compensate for playback when the device is difficult to play a small domain-specific bass sound characteristics to achieve more natural playback of programmable equalizer, allowing improve all portable VGP-BPS9 B , VGP-BPS9 S devices recording, playback quality. “
