TP3420AV309 Description

Short technical summary and product information.

The TP3420AV309 from Texas Instruments is a monolithic transceiver designed for data transmission on twisted pair subscriber loops, specifically for ISDN basic access at the 'S' and 'T' interfaces. It supports full-duplex transmission at 192 kb/s using AMI line coding, providing 2 'B' channels of 64 kb/s and 1 'D' channel of 16 kb/s, along with multiframe channels for Layer 1 maintenance.

 

This device is built on a 1.0-micron double-metal CMOS process and requires a single +5V supply. It can be configured to operate as Terminal Equipment (TE), Network Termination (NT-1 or NT-2), or as a PABX line-card or trunk-card device. The TP3420AV309 supports various I.430 wiring configurations, including passive bus and point-to-point connections up to 1.5 km. Its adaptive receive signal processing ensures high noise immunity.

 

The TP3420AV309 is supplied in a 20-PLCC package and is designed for surface mounting. It offers selectable TE or NT modes and features adaptive and fixed timing options. The device is compatible with MICROWIRE™ and SCP serial control interfaces and can interface with codecs/filters like the TP3054/7.
