Memory Clock Divided by Two. This signal is the
Memory Clock input divided by two. It assists the
host subsystem in synchronizing DMA events.
Clock. The 12MHz input clock requires a 50%
±
10% duty cycle with an accuracy of
±
0.01%. The accuracy
is required in order to meet the Manchester encoding/
decoding requirements of MIL-STD-1553.
Memory Clock. This is the input clock frequency the BCRTM
uses for memory accesses. The memory cycle time is equal
to two MCLK cycles. Therefore, RAM access time is
dependent upon the chosen MCLK frequency (6MHz
minimum, 12MHz maximum). Please see the BCRTM DMA
timing diagrams in this data sheet.
