General Description
SEQUENCER is a page oriented clock pattern sequencer with a quartz time base of 50ns. The Sequencer system processor is a 32-bit transputer (T425) with 8 Mbytes DRAM. The words of a page are sequentially output, each word has an individual time count. Pages are held in a SRAM, 32K deep and 64Bits wide. Bit 0 to 6 determine the lifetime of the pattern and Bit 15, if set, states the end of a page. Bit 16 to 63 of a word are output as digital clocks, so there are 48 TTL clocks available. The maximum page length is 128 words. The time per word is between 50ns and 3.5 us, depending on Bit 0 to 6.
