Abstract: data transfer bit rate is T = 1/Freq. For the S T 506 drive, Freq. = 5 M H z and th e flux transitions , with afreq uency of 20 times the half-bit cell time. Th e V C O runs nominally at 20 M H z since the , inactive, the VC O will be locked to a crystal controlled signal of 5 M H z. Since th e H D C 9 2 2 7 , Ioh = 400uA (All outputs except lO M H zO U T and 5M H zO U T ) lO = 4 0 0 uA (lO M H z O U T and 5 M , FIGURE 4 r 1 IT FIGURE 5 FIGURE 6 — / IOM H z O UT ■ v_/ \ V f ...
