Megjegyzések:	The current CMS silicon pixel detector as the innermost component of the CMS ex-periment is performing well at LHC design luminosity, but would be subject to severe inefficienciesat LHC peak luminosities of 2?1034cm?2s?1.Therefore, an upgrade of the CMS pixel detector is planned, including a new readout chip.The chip design comprises additional on-chip buffer cells as well as high-speed data links and low-threshold comparators in the pixel cells. With these changes the upgraded pixel detector will beable to maintain or even improve the efficiency of the current detector at the increased requirementsimposed by high luminosities and pile-up.The effects of these design changes on e.g. position resolution and charge collection efficiencywere studied in detail using a precision tracking telescope at the DESY test beam facilities. Thehigh telescope track resolution enables precise studies of tracking efficiency, charge sharing andcollection even within single pixel cells of the device under test.This publication focuses on the improved performance and capabilities of the new pixel read-out chip and summarizes results from test beam campaigns with both unirradiated and irradiateddevices. The functionality of the chip design with its improved charge threshold, redesigned datatransmission and buffering scheme has been verified.
