19.44 Mbyte/s Parallel Datacom
The Rx Terminal Port Parallel 19.44 Mbyte/s Datacom Format is shown, generically, in Figure 65, which repre-
sents the complete bus structure. In actual operation the PHAST-1 would only supply one third of the output
information as was shown in Figure 59. The Reference inputs must be RRCI and RRFI. RRFI may be from one
to three clock periods in duration. TPCO is the 19.44 MHz output clock. TPDO0 through TPDO7 are the byte
wide data outputs where the LSB is TPDO0. RSPE is Low during the TOH and, optionally, the POH Byte times.
The POH Byte option is controlled by ENDCMPOH. When set to "1", RSPE remains High during these Byte
times. A value of "0" results in RSPE transitioning Low during these Byte times. RSYN is High during the C1
(all three slots), J1 and, optionally, V1 Byte times. The V1 Byte time option is enabled when the control H4INT
is set to "1". The polarity of TPCO can be inverted with the control INVPCK. A value of "0" results in TPDO(0-
7), RSPE, RSYN and TPARO being output on the Falling Edge. When INVPCK = "1", the information is output
on the Rising Edge of TPCO.
