N682386/87 + N681622

Dual Programmable Extended Codec/SLCC + SLFC

1. DESCRIPTION

The N682386/87, implements a dual channel FXS telephone line interface optimized for short loop applications. It

integrates SLCC (Subscriber Line Control Circuit) functionality with a dual programmable CODEC and a dual DC/DC

controller. The SLCC supports internal ringing up to 90 V_PK(5 REN at 4k ft) ideal for Customer Premise Equipment

(CPE). The CODEC can be configured for μ-law, A-law or 16-bit linear PCM encoding. It also supports a

comprehensive set of signaling capabilities required to supervise and control the telephone lines. These include tone

generation, ring tones, DTMF detection/ generation as well as FSK generation. An on-chip Pulse Width Modulation

(PWM) driver allows control of an inductor based DC/DC converter. Programmable impedance and trans-hybrid

balancing allow for worldwide deployment.

! WARNING !

HIGH VOLTAGE WARNING USE EXTREME CAUTION

Digital interfaces

PCM: G.711 μ-Law, A-Law and 16-bit linear

GCI and SPI bus

High voltage sources could cause serious injury or

death if not used in accordance with design and/or user

specifications, if they are used by untrained or

unqualified personnel. Before testing Nuvoton’s products

read and understand all instructions, and safety

procedures as in industry standard safe practices.

Programmable audio path gains

Both PCM Master and Slave modes supported

On-chip PLL for flexible clocking options including

1.0 MHz and 2.0 MHz BCLK operation

Operating voltage: 3.3V
