3.5.1 Baseband Transmit Section
1. The AD6535 Baseband Transmit Section is designed to support GMSK for both single-slot and
multi-slot application.
2. The AD6535 includes a digital GMSK modulator which is used for GSM application. The GMSK
modulator uses a ROM lookup table to modulate the serial data stream ffrom the BSPORT. The
GMSK modulator is based on 3GPP TS 45.004 ver.5.1.0 Release 5
3.5.2 Baseband Receive Section
1. This section consists of two identical ADC channels that process baseband in-phase(I) and
quadrature(Q) input signals.
