AD8345 IC Usage for OQPSK Modulation

Hello, 

We are currently designing a ground-to-satellite communication system by OQPSK (Offset Quadrature Phase Shift Keying) modulation. As you know, in comparison to QPSK modulation, Q-channel data shall be delayed by time of Tb in OQPSK with the respect to I-channel. 

We are curious about that is it possible to provide OQPSK modulation by AD8345 IC? If so, is there any kind of application note / sample application? We're confused about providing time delay offset to Q channel for AD8345 IC, perhaps adding delay to data bus from the AD9761 TxDAC on Q channel is sufficient?

Looking forward for your reply

Best regards
