Overview
The TP3067WM/63SN is a monolithic PCM CODEC and Filter COMBO utilizing A-law encoding. It integrates transmit high-pass and low-pass filtering, receive low-pass filtering with sin x/x correction, active RC noise filters, and an internal precision voltage reference. The device features a serial I/O interface, auto-zero circuitry, and receive push-pull power amplifiers for balanced output drive. Designed for D3/D4 and CCITT applications, it operates on a single ±5V supply with typical active power consumption of 70 mW and standby power of 3 mW.
Feature Summary
- Integrated CODEC system with transmit and receive filtering
- A-law compatible encoder and decoder
- Receive push-pull power amplifiers for balanced line drive
- Internal auto-zero circuitry and precision voltage reference
Applications
- D3/D4 telephony systems
- CCITT standard communication applications
- Subscriber line interface circuits
Procurement Notes
Verify the specific suffix /63SN against the manufacturer's official documentation to confirm package type and temperature range specifications. Ensure compatibility with National Semiconductor (now Texas Instruments) legacy product lines when sourcing replacements or verifying authenticity.
Selection Notes
Select this component for applications requiring A-law PCM encoding rather than µ-law. Confirm that the system design supports the required ±5V dual power supply configuration. Verify that the serial interface timing requirements align with the master clock and bit clock specifications provided in the datasheet.
Part Context
This part belongs to the TP3064/TP3067 family of Enhanced Serial Interface CMOS CODEC/Filter COMBOs. The TP3067 variant specifically implements A-law compression and expansion algorithms, distinguishing it from the µ-law based TP3064 model within the same functional architecture.
Replacement Considerations
Consult official replacement guides for equivalent National Semiconductor or Texas Instruments legacy CODECs. Verify pinout compatibility and electrical characteristics before substituting.
