GENERAL DESCRIPTION The W682510 and W682310 are general-purpose dual channel PCM CODECs with pin-selectable μLaw or A-Law companding. The device is compliant with the ITU G.712 specification. It operates from a single power supply (+5V for the W682510, +3V for the W682310) and is available in 20-pin SSOP, and 24-pin SOP package options. Functions performed include digitization and reconstruction of voice signals, and band limiting and smoothing filters required for PCM systems. The filters are compliant with ITU G.712 specification. The W682510 and W682310 performance is specified over the industrial temperature range of –40°C to +85°C. The W682510 includes an on-chip precision voltage reference and receive output buffer amplifiers, capable of driving 600Ω loads (line transformers.) The analog section is fully differential, reducing noise and improving the power supply rejection ratio. The data transfer protocol supports either parallel or serial synchronous communications for PCM applications. The W682510 and W682310 have a build in PLL that eliminates the need for a master clock and automatically determines the division ratio for the required internal clock. For fast evaluation and prototyping purposes, the W682510DK & W682310DK development kits are available. 2. FEATURES Single power supply o ...
