L9218A規(guī)格書詳情

Description

This general-purpose electronic subscriber loop interface circuit (SLIC) is optimized for low cost, while still providing a satisfactory set of features.

The L9218 is pin-for-pin compatible with the Agere L9219 and L9217 SLICs.

The L9218 requires a 5 V power supply and single battery to operate. This is a forward battery only device. Additionally, a low-power scan mode, wherein all circuitry except the off-hook supervision is shut down to conserve power, is available.

Features

■ Basic forward battery only SLIC functionality at a low cost

■ Pin compatible with Agere Systems Inc. L9219 and L9217 SLIC

■ Low active power (typical 138 mW during on-hook transmission)

■ Low-power scan mode for low-power, on-hook power dissipation (59 mW typical)

■ Minimal external components

■ Distortion-free, on-hook transmission

■ Convenient operating states:

— Forward battery low current limit

— Forward battery high current limit

— Low-power scan

— Disconnect (high impedance)

■ Adjustable supervision functions:

— Off-hook detector with hysteresis

— Ring trip detector

■ Logic controlled high and low current limit

■ Two gain options to optimize the codec interface

■ Thermal protection with thermal shutdown indication
