The AD7011 is a complete low power CMOS π/4 DQPSK modulator with single +5 V power supply. The part is designed to perform the baseband conversion of I and Q transmit wave- forms in accordance with the American Digital Cellular Tele- phone system (TIA IS-54).

The AD7010 is a complete low power, CMOS, π/4 DQPSK modulator with single +5 V power supply. The part is designed to perform the baseband conversion of I and Q transmit waveforms in accordance with the Japanese Digital Cellular Telephone system. The on-chip π/4 Differential Quadrature Phase Shift Keying (DQPSK) digital modulator, which includes the Root Raised Cosine filters, generates I and Q data in response to the transmit data stream. The AD7010 also contains ramp control envelope logic to shape the I and Q output waveforms when ramping up or down at the beginning or end of a transmit burst. Besides providing all the necessary logic to perform π/4 DQPSK modulation, the part also provides reconstruction filters to smooth the DAC outputs, providing continuous time analog outputs. The AD7010 generates differential analog outputs for both the I and Q signals. As it is a necessity for all digital mobile systems to use the lowest possible power, the device is designed in a low power manner.

The AD7008 is a CMOS DDS Modulator features a single +5 V supply, 32-Bit Phase Accumulator, On-Chip COSINE and SINE Look-Up Tables, On-Chip 10-Bit DAC, Frequency, Phase and Amplitude Modulation, Parallel and Serial Loading, Software and Hardware Power Down Options, 20 MHz and 50 MHz Speed Grades.
