13 13 31 Mar. 2009Martin Postranecky / Matt Warren CCC - Timing Overview CCC - Timing Overview C+C provides a fast clock ( CLOCK )C+C provides a fast clock ( CLOCK ) – Assumed to be ~50 MHz, local or machine – Stand-alone clock can be 50 or 100 MHz CCC does NOT support varied delays on individual outputsCCC does NOT support varied delays on individual outputs CCC card can adjust timing of synchro-signals wrt. CLOCKCCC card can adjust timing of synchro-signals wrt. CLOCK

14 14 31 Mar. 2009Martin Postranecky / Matt Warren CCC - Link Interface CCC can connects to LDA, DIF and ODR using the ‘standard’ HDMI cabling and connectors and pinout ( Clink )CCC can connects to LDA, DIF and ODR using the ‘standard’ HDMI cabling and connectors and pinout ( Clink ) – But only a subset of the signals/functions used – CCC can be used as a pseudo-LDA for stand-alone DIF testing A distinction is made between fast and fixed latency signals.A distinction is made between fast and fixed latency signals. – Fast signaling is asynchronous and uses a dedicated line to transfer a pulse. No attempt is made to encode data pulse. No attempt is made to encode data – Fixed-latency signaling will not arrive fast, but will arrive a known latency after reception by CCC latency after reception by CCC HDMI Signals CLink SignalDirectionFunctionType CLOCK_L2D LDA → DIF Distributed DIF ClockSTP DATA_L2D LDA → DIF Data to DIF (mainly configuration)STP DATA_D2L DIF → LDA Data from DIF (mainly events)STP ASYNC_L2D LDA → DIF Asynchronous triggerUTP* GEN_D2L DIF → LDA General useSTP * Twisted pair not guaranteed by HDMI specification but seen in commercial cables
