描述 Description

GENERAL DESCRIPTION
TheAD6426 Enhanced GSM Processor (EGSMP) is the central component of the highly integrated AD20msp425 GSM Chipset. Offering a low total chip count, low bill of materials cost and long talk and standby times, the chipset offers designers a straightforward route to a highly competitive
product in the GSM/DCS1800 market. The EGSMP performs all the baseband functions of the Layer 1 processing of the GSM air interface. This includes all data encoding and decoding processes as well as timing and radio sub-system control functions.FEATURES
