Overview
The W6811ISG TR is a single-channel PCM voiceband codec manufactured by Nuvoton Technology Corporation. It operates within a voltage range of 2.7 V to 3.3 V and supports both 5V and 3V logic levels. The device is housed in a 24-pin SOP package. It features pin-selectable u-law or A-law companding and complies with the ITU G.712 standard. The internal signal processing includes a 3.4 kHz low-pass filter followed by a high-pass filter with a 200 Hz cut-off frequency, designed for standard voiceband applications.
Feature Summary
- Supports pin-selectable u-law or A-law companding modes
- Complies with ITU G.712 standards for voiceband processing
- Integrates specific low-pass and high-pass filtering stages
Applications
- Voiceband audio interface circuits
- PCM communication systems
- Telecommunications equipment requiring single-channel codec functionality
Procurement Notes
Verify component status as this part may be marked Not For New Designs. Confirm RoHS compliance and lead-free status through official documentation. Ensure the 24SOP package variant matches system requirements. Cross-reference datasheet revisions to confirm electrical specifications and pinout definitions before integration.
Selection Notes
Select this component for single-channel PCM voiceband applications requiring specific ITU G.712 compliance. Consider the 2.7 V to 3.3 V operating range and 24-pin SOP form factor. Evaluate the integrated filter characteristics against system bandwidth needs. Verify availability status due to potential design retirement classifications.
Part Context
The W6811 series represents general-purpose single-channel PCM codecs from Nuvoton. The ISG suffix indicates the specific SOP-24 package configuration. This component belongs to the broader family of audio interface ICs designed for telecommunications and voice processing tasks.
Replacement Considerations
Check for direct substitutes within the W681x series. Verify compatibility of pinouts and companding options when considering alternative single-channel voicecodecs.
