AUSTIN, TX – June 11, 2002 – Cirrus Logic (Nasdaq: CRUS), a premier supplier of high-performance analog and DSP chip solutions for consumer entertainment electronics, announced today that it is in full production of the new CS61884 T1/E1/J1 Octal Line Interface Unit (LIU), the latest and most feature-rich addition to its LIU product family of telecommunications solutions.

The CS61884 builds on Cirrus’ patented matched impedance technology, which completely eliminates the need to change external components between 75-ohm, 100-ohm and 120-ohm mode designs. The simplified, single circuit design reduces component count and the manufacturing bill of materials (BOM) for telecommunication customers. This allows manufacturers to support all major international telecommunications protocol standards in one “universal T1, E1, J1” functional line card while providing savings on materials, engineering, qualification and procurement efforts.

The CS61884 builds on the tremendous success of Cirrus’ LIU family and continues a decade-long legacy of outstanding telecommunications solutions. “As high bandwidth optical technology continues to drive telecom network expansion, the new Cirrus CS61884 Octal LIU provides the high port densities required by our customers,” said Lew Paceley, vice president of marketing for the Crystal Products Division. “Our new Octal LIU brings industry standard compatibility with the added benefits of our matched impedance technology.”

The CS61884 integrates eight full-featured LIU channels in an industry standard footprint and firmware compatible IC. Each channel has complete receiver and transmitter circuitry including crystal-less path-selectable jitter attenuation, full encoder/decoder circuitry, Loss of Signal detection, and Alarm Indication Signal warnings. In addition, there is an Arbitrary Waveform Generator allowing user-customized transmit pulse shapes.

Pricing and Availability

The CS61884 is one of three new Octal port additions to the LIU family of devices, the others being the CS61881 Octal E1 AFE and the CS61880 Octal E1 LIU. All three are currently shipping in volume production. The CS61884 is available in 144-pin LQFP and 160-pin FBGA packages. CS61884 pricing starts at $25.03 for the LQFP in 10,000 OEM quantities.
