Gary, some more news for you on Qcom. SAN DIEGO - April 30, 1996 - QUALCOMM Incorporated, (NASDAQ: QCOM) today announced the availability of a single-chip vocoder that utilizes PureVoice_, the latest version of the proprietary 13 kilobit QUALCOMM Code Excited Linear Predictive (QCELP-13) speech coding algorithm. PureVoice, named for its near landline voice quality, was developed for use in QUALCOMM's cellular and Personal Communications Services (PCS) products featuring the Company's Code Division Multiple Access (CDMA) technology. As a single-chip solution, part number Q4413, PureVoice is ideal for a wide range of voice compression applications including voice mail, land-mobile radios, satellite communications, secure communications and high compression digital recording. The Q4413 supports full-duplex operation in both fixed and variable rate modes. In fixed rate mode, the vocoder can operate at data rates of 13.3 kilobits/second or 6.2 kilobits/second. In variable rate mode, the Q4413 continuously chooses among four coding rates on a frame-by-frame basis to guarantee the best voice quality at the lowest data rate. Speech pauses are encoded at 800 bits/second, while voice is encoded at 13.3, 6.2 or 3.1 kilobits/second. The vocoder detects when the background noise level changes and dynamically adjusts its test parameters to maintain the optimal data rate and voice quality. The user can also customize the way variable rates are chosen to meet the data rate requirements of a particular application. For telecommunications applications, an optional G.165 network echo canceller and Dual Tone Multi Frequency (DTMF) support are included on the chip. Pricing for the Q4413I-1S1 in 100 piece quantities is $69.00 per device. Production quantities will be available in late June 1996.
