Aug 27, 2012 Data transmission: frame word Every time coarse counter rolls over after 2048 clk_dll cycles a frame word is sent at the next available word slot. Every time coarse counter rolls over after 2048 clk_dll cycles a frame word is sent at the next available word slot. clk_dll frequency where the coarse counter and the frame counter is advanced can in principle be different from the clk_sync frequency. clk_dll frequency where the coarse counter and the frame counter is advanced can in principle be different from the clk_sync frequency. The time intervall between two frames depends mainly on clk_dll. However, once a frame request is initiated in the clk_dll domain, this request is ported into the clk_sync domain and is executed at the next word transmission cycle which has a period of 6 clk_sync cycles. The time intervall between two frames depends mainly on clk_dll. However, once a frame request is initiated in the clk_dll domain, this request is ported into the clk_sync domain and is executed at the next word transmission cycle which has a period of 6 clk_sync cycles. Thus in nominal conditions (clk_sync & clk_dll = 320 MHz) the frame is sent out in average each (1/320 MHz * 2048 =) 6.4 µs. However as 2048 cycles cannot be divided 6 (number of 8b10b words in each data word) the number of word transmission cycles between two frame words toggles between 341 and 342 (2 * 341 and 1 *342 or 2 * µs and µs). Thus in nominal conditions (clk_sync & clk_dll = 320 MHz) the frame is sent out in average each (1/320 MHz * 2048 =) 6.4 µs. However as 2048 cycles cannot be divided 6 (number of 8b10b words in each data word) the number of word transmission cycles between two frame words toggles between 341 and 342 (2 * 341 and 1 *342 or 2 * µs and µs). The frame word is defined as follows: The frame word is defined as follows: word_frame0(27 downto 0)<= frame_counter; word_frame0(27 downto 0)<= frame_counter; word_frame0(36 downto 28)<= hit_counter; word_frame0(36 downto 28)<= hit_counter; word_frame0(42 downto 37)<= qchip_collision_count; word_frame0(42 downto 37)<= qchip_collision_count; word_frame0(46 downto 43)<= “0000” not used; word_frame0(46 downto 43)<= “0000” not used; word_frame0(47)<= '1';--format bit word_frame0(47)<= '1';--format bit A.
