 the INV and NON_INV blocks must have  same clock speed ?, this affects the The switched capacitor block?

The input stages are CT blocks, so clock is irrelevant to NI column. So just

   

one column clock for the one containing SC output block. From datasheet here is

Three Op-Amp Topology

   

The three opamp circuit topology employs a pair of continuous time PSoC blocks and a single switched capacitor PSoC block. The two continuous time blocks, INV and NON_INV, are placed in a pair of columns in the same manner as the two opamp topology. The CONVERT block maps onto a switched capacitor PSoC block immediately underneath one of the two continuous-time blocks. Internal block-to-block connections limit the number of arrangements to three for any given column pair.
