The highly integrated IC provides developers with a space-saving solution that streamlines product development, reduces design complexity and lowers overall system costs compared to boards that use multiple stereo A/D converters for surround-sound or multichannel designs. The end result? Smaller audio equipment that can be produced at a lower cost compared to today’s products. • • • • • • • • • The CS5368 is the industry’s first audio A/D converter to support a high-speed TDM interface which provides a serial output of 8 channels of audio data with sample rates up to 192 kHz within a single data stream. This capability reduces layout complexity and relieves input/output constraints in digital signal processors. The on-chip level-shifter and oscillator driver further reduce complexity and simplify system design. The IC also features a differential architecture that provides excellent noise rejection and performs sampling, analog-to-digital conversion and anti-alias filtering. A/V Receivers Home theater systems Digital mixing consoles Multi-track recording systems Broadcast studio equipment Digital effects processors Outboard audio converters PC sound cards Automotive audio systems The CS5368 uses a 5th-order, multi-bit Delta-Sigma architecture that provides superior 114 dB dynamic range and negligible distortion. Low-latency digital filtering, with the industry’s shortest group delay, further preserves the original audio quality and experience, making the ICs ideal for real-time and live-sound applications. The flagship CS5368 is an 8-channel converter and the CS5364 and CS5366 are its pin-compatible 4- and 6-channel family members. Competitively priced at $11.61 in quantities of 10K units, the CS5368 is an ideal solution for audio engineers who desire high-end fidelity at a competitive price. www.cirrus.com C i r r u s L o g i c , I n c . · 2 9 0 1 V i a F o r t u n a · A u s t i n T X 7 8 74 6 U S A · T 5 1 2 - 8 5 1 - 4 0 0 0 · T 8 0 0 - 8 8 8 - 5 0 1 6 · F 5 1 2 - 8 5 1 - 4 9 7 7 Product Bulletin 0163-0605-PB-LP © 2005 Cirrus Logic, Inc.
