Description and Introduction

Enhanced Serial Interface CMOS CODEC/Filter COMBO **Manufacturer:** NS (National Semiconductor)  

**Part Number:** TP3064J  

### **Specifications:**  
- **Type:** PCM Codec-Filter (Pulse Code Modulation)  
- **Function:** Combines a transmit filter, receive filter, and PCM codec in a single chip.  
- **Interface:** Serial PCM interface compatible with T1 and CEPT primary rate systems.  
- **Sampling Rate:** 8 kHz (standard telephony rate).  
- **Resolution:** 13-bit linear or 8-bit compressed (μ-law/A-law) PCM data.  
- **Power Supply:** Single +5V supply.  
- **Power Consumption:** Low power operation.  
- **Package:** 16-pin DIP (Dual In-line Package).  

### **Descriptions and Features:**  
- **Transmit Path:** Includes a preamplifier, anti-aliasing filter, and ADC (Analog-to-Digital Converter).  
- **Receive Path:** Includes a DAC (Digital-to-Analog Converter), smoothing filter, and power amplifier.  
- **Compliance:** Meets CCITT G.711, G.712, and AT&T D3/D4 specifications.  
- **Applications:** Used in digital telephony, T1/E1 line cards, and PCM voice processing systems.  
- **Additional Features:**  
  - On-chip precision voltage reference.  
  - Programmable gain settings.  
  - Internal timing generation.  

This part is now obsolete but was widely used in telecommunications equipment.
