W682510/W682310
1. GENERAL DESCRIPTION
The W682510 and W682310 are general-purpose dual channel PCM CODECs with pin-selectable
μ
-
Law 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 PDIP
(W682510 only), 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 600
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.
