Receive Line Ring Port Clock: The LRPRXFS and
LRPRXDATA signals are clocked out on the rising
edges of this clock.
Its frequency is 19.44 MHz.
Receive Line Ring Port Frame Sync: An active high,
one LRPRXCLK clock-cycle wide frame sync pulse that
identifies the first bit in the data stream present on
LRPRXDATA.
Receive Line Ring Port Data: A serial frame contain-
ing the remote information, REI and RDI, for the individ-
ual high order path signals.
Receive Polled-PHY Packet Available: High when a
predefined minimum number of words or a complete
packet is available in the polled Rx FIFO, otherwise low.
It is driven when a matching PHY address is presented
on PPUTRXADDR.
Tristated when either the null-PHY address or a not
matching PHY address is presented on PPUTRXADDR.
POS-PHY Standard notation: PRPA
Transmit Line Ring Port Clock: The LRPTXFS and
LRPTXDATA 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-12P device, it must be tied to VSS.
Transmit Line Ring Port Frame Sync: An active high,
one LRPTXCLK clock-cycle wide frame sync pulse that
identifies the first bit in the data stream present on
LRPTXDATA.
When this lead is not connected to LRPRXFS of a mate
PHAST-12P device, it must be tied to VSS.
