Transmit TOH Port Data: The value of the TOH byte
requested by TOHTXADDR is clocked in as the 8 consec-
utive states while TOHTXDLE is high.
When the Transmit TOH Byte Interface is not used, this
lead must be tied to VSS.
Transmit HO POH Port Clock: The POHTXALE,
POHTXDLE and POHTXADDR signals are clocked out
on the falling edges of this clock.
POHTXDATA is clocked in on the rising edge of this clock.
Its frequency is 77.76 MHz.
Transmit HO POH Port Address Latch Enable: An
active high, 8 POHTXCLK clock-cycle wide pulse indicat-
ing that a valid address is present on POHTXADDR.
Transmit HO POH Port Address: The 8 consecutive
states clocked out while POHTXALE is high form the
address of the subsequent High Order POH byte
requested on the POHTXDATA lead.
Receive HO POH Port Clock: The POHRXALE,
POHRXDLE, POHRXADDR and POHRXDATA signals
are clocked out on the falling edges of this clock.
Its frequency is 77.76 MHz.
Receive HO POH Port Address Latch Enable: An
active high, 8 POHRXCLK clock-cycle wide pulse indi-
cating that a valid address is present on POHRXADDR.
Receive HO POH Port Address: The 8 consecutive
states clocked out while POHRXALE is high form the
address of the subsequent High Order POH byte sent
on the POHRXDATA lead.
Receive HO POH Port Data Latch Enable: An active
high, 8 POHRXCLK clock-cycle wide pulse indicating
that valid data is present on POHRXDATA.
Receive HO POH Port Data: The 8 consecutive states
clocked out while POHRXDLE is high form the value of
the High Order POH byte addressed by POHRXADDR.
