DS2196

T1 Dual Framer LIU

Dallas Semiconductor -> Maxim Integrated 

DS2196

1 INTRODUCTION

The DS2196 is a derivative of the DS21352 T1 Single Chip Transceiver. The feature set has been

optimized for transport applications commonly found in T1 transmission equipment. The DS2196

register map and register bit definitions are compatible with the DS21352/DS21552 allowing for easy

migration to the DS2196. Interface designs requiring per channel code insertion, elastic stores, and ANSI

1’s density monitoring should use the DS21352 or DS21552.
