San Jose, CA--July 22, 1996--VLSI Technology Inc. (San Jose, CA) introduced the VL82C801 audio codec as the first in a series of PC-based multimedia products.
The VL82C801 features low voltage operation, advanced FIR (finite impulse response) filters, and a 0.6 m single-poly silicon manufacturing process. The single-poly silicon process makes it possible to implement the VL82C801 codec as an ASIC functional system block (FSB) in system level integration-scale custom and semicustom circuits.
This codec is pin and register compatible with codecs such as the CS4231 and AD1848 series designs. VL82C801 codec features include Microsoft Windows sound system compatibility, on-chip FIFO for capture and playback, byte-wide integrated ISA interface, and 4 to 50 kHz 16-bit sample rates.
Additional features include ADPCM compression and decompression, micronLaw and ALaw compression/decompression, MPC Level 2-compatible mixer (four stereo channels, one mono), dual-DMA operation for full duplex, 24 mA bus drive capability, 3.0 V to 5.0 V single voltage operation, programmable gain and attenuation, signal-to-noise ration in excess of 80 dB over the 20 kHz audio spectrum and general purpose timer for audio-visual synchronization.
The VL82C801 codec will sample in September 1996, with production in the fourth quarter of 1996. Pricing for the 10k-unit quantities is $8.
