Full TV PAL is 768x576 @ 52.000µs @ 14,7692307Mhz (= quadra pixels)
ITU samplingrate is 13,5 Mhz (= squarepixels)

14,7692307/13,5 = 1,094017 = TV PAR @ 13.5Mhz used by a SAP

or ...
52.000µs * 13.5Mhz = 702 active pixels at square pixels
52.000µs * 14,7692307Mhz = 768 active pixels at quadra pixels

768/702 equals 128/117 equals 1,094017
