SmartDV’s PCM Controller IP is a silicon-proven, fully featured Pulse Code Modulation bus controller solution purpose-built for SoC designs requiring standardized digital audio connectivity to telecom basebands, Bluetooth audio codecs, and legacy voice-codec interconnects across consumer, mobile, and communications applications. Implementing the industry-standard PCM highway interface with both Short Frame Sync and Long Frame Sync modes, and supporting ITU-T G.711 A-law and μ-law companding, it delivers a compact, production-tested controller for the narrowband and wideband voice-audio interconnects used across Bluetooth SCO/eSCO links, GSM/telecom basebands, and legacy voice-codec designs.
Designed for the practical integration requirements of voice-audio SoC designs, the IP supports configurable master and slave clock generation, programmable time-slot allocation for multi-channel TDM-style operation over a shared PCM link, and both linear and companded (A-law/μ-law) sample formats for interoperability with narrowband telecom codecs and Bluetooth audio hardware. Its configurable frame sync polarity, slot width, and clock/frame timing give communications and consumer SoC teams a flexible, standards-aligned PCM interconnect for voice-path audio integration.
Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its parameterized slot and clocking architecture and clean host interface enable fast integration across a wide range of process nodes and target applications.
