Arduino Mega and QT1106


I would like interfaçing a QT1106 Qtouch sensor with my Arduino Mega board. My application doesn't run, i think i have a problem with the SPI clock. On Qt1106 datasheet the max clock rate is 70kHz but with the Arduino Mega the lowest clock value is Fosc/128 = 16MHz/128 = 125 kHz. Somebody can help me ?

Best regards
