LE88010BQC

The Zarlink Semiconductor Inc LE88010BQC is a Single Channel VoicePort SLAC (Subscriber Line Audio Controller) device. In combination with a DAA, it provides a complete phone line termination-to-digital interface solution. This device is designed for applications such as voice-enabled DSL modems, Voice over IP/ATM, Integrated Access Devices (IAD), and Set-Top Boxes with PSTN Line Interface.

Key features include a fully programmable SLAC device, line supervision capabilities, and support for DTMF tones and dial pulses. It also includes an integrated 150 mW 3-V or 5-V relay driver, which supports lifeline POTS in DSL IAD applications. The device is housed in a compact 44-pin QFN package, requiring minimal external discrete components.

This SLAC device offers programmability for various signaling features, including two-wire AC impedance, input/output mode selection for relay drivers and general-purpose digital I/O pins, and adaptation to all ringing frequencies. It supports DTMF tone generation, dial pulse generation, caller ID pass-through, and numeric address signaling.

The LE88010BQC is ideal for reducing system cost, space, and power consumption due to its high level of voice integration and programmable features. Designers benefit from a simple, cost-effective, low-power, and dense interface design without sacrificing functionality.
