The KIV-14 is a Collateral Message Organization System (CMOS) Large Scale Integrated Circuit (LSIC) device that provides encryption of digitized voice and low-speed data signals for securing classified or sensitive information. The module can accommodate high error rate environments and supports a wide range of commonly used voice coding schemes such as Continuously Variable Slope Delta (CVSD), Linear Predictive Coding (LPC), RELP, and Pulse Code Modulation (PCM). The KIV-14 provides half-duplex encryption/decryption and is cryptographically compatible with the following COMSEC equipment: KY-57/58, KYV-2A/B, KYV-5, KY-99/99A, KG-84, Single Channel Ground and Airborne Radio System (SINCGARS), Secure Telephone Unit Third Generation (STU-III), RAILMAN, and the Windster COMSEC Module. The KIV-14 is a 68-pin, J-leaded package designed for embeddment within low-speed digital telephone modems, mobile telephones, paging equipment, and hand-held portable radios. Modes of operation, from which the host equipment developer can select, include clock and data recovery, out-of-sync detection, initial synchronization error correction, and resynchronization. The KIV-14 is an UNCLASSIFIED controlled cryptographic item (CCI) approved by the Government to secure communications up to the TOP SECRET level.
