Receive TOH Port Clock: The TOHRXALE, TOHRX-
DLE, TOHRXADDR and TOHRXDATA signals are
clocked out on the falling edges of this clock.
Its frequency is 77.76 MHz.
Receive TOH Port Address Latch Enable: An active
high, 10 TOHRXCLK clock-cycle wide pulse indicating
that a valid address is present on TOHRXADDR.
Receive TOH Port Address: The 10 consecutive
states clocked out while TOHRXALE is high form the
address of the subsequent TOH byte sent on the
TOHRXDATA lead.
Receive TOH Port Data Latch Enable: An active high,
8 TOHRXCLK clock-cycle wide pulse indicating that
valid data is present on TOHRXDATA.
Receive TOH Port Data: The 8 consecutive states
clocked out while TOHRXDLE is high form the value of
the TOH byte addressed by TOHRXADDR.
Transmit HO Ring Port Clock: The PRPTXFS and
PRPTXDATA signals are clocked in on the rising edges
of this clock.
Its frequency is 19.44 MHz.
When this lead is not connected to LRPRXCLK of a
mate PHAST-12N device, it must be tied to VSS.
Transmit HO Ring Port Frame Sync: An active high,
one PRPTXCLK clock-cycle wide frame sync pulse that
identifies the first bit in the data stream present on
PRPTXDATA.
When this lead is not connected to LRPRXFS of a mate
PHAST-12N device, it must be tied to VSS.
Transmit HO Ring Port Data: A serial frame contain-
ing the remote information, REI and RDI, for the individ-
ual high order path signals.
When this lead is not connected to LRPRXDATA of a
mate PHAST-12N device, it must be tied to VSS.
