چکیده انگلیسی
This paper describes the recent development of a gigabit data transmitter for the Belle-II pixel detector (PXD). The PXD is an innermost detector currently under development for the upgraded KEK-B factory in Japan. The PXD consists of two layers of DEPFET sensor modules located at 1.8 and 2.2Â cm radii. Each module is equipped with three different ASIC types mounted on the detector substrate with a flip-chip technique: (a) SWITCHER for generating steering signals for the DEPFET sensors, (b) DCD for digitizing the signal currents, and (c) DHP for performing data processing and sending the data off the module to the back-end data handling hybrid via â¼40cm Kapton flex and 12-15Â m twisted pair (TWP) cables. To meet the requirements of the PXD data transmission, a prototype of the DHP data transmitter has been developed in a 65-nm standard CMOS technology. The transmitter test chip consists of current-mode logic (CML) drivers and a phase-locked loop (PLL) which generates a clock signal for a 1.6Â Gbit/s output data stream from an 80Â cm reference clock. A programmable pre-emphasis circuit is also implemented in the CML driver to compensate signal losses in the long cable by shaping the transmitted pulse response. The jitter performance was measured as 25Â ps (1Ï distribution) by connecting the chip with 38Â cm flex and 10Â m TWP cables.
