AD9951 DDS quadrature (IQ) generator

This is my quadrature generator for use in phasing SSB radio.
It's two PCB's concept of Stefan DL5MGD http://www.dl5mgd.de/dds/AD9951.htm and built by Krzysztof SQ8Z.
My work is Atmel AVR ATMega32 based controller.
Idea is simple, the two AD9951's have one clock source and receive same frequency settings in same time.
Only the "data" wire is split which gives me the ability to initialize the differently. One goes with SINe function and other with default COSine (Control Function Register 1 of AD9951 and 0x00001000 bit)
