Function
RATM_CLAV/TPHY_CLAV
Bidi
U23
ATM
: Receive UTOPIA ATM Layer
Cell Available is an active high
signal asserted by the PHY layer to
indicate that there is a cell available
to send.
PHY
: Receive UTOPIA/Any-PHY
PHY Layer Cell Available is an
active high signal asserted by the
AAL1gator-32 to indicate there is a
cell-space available. The
AAL1gator-32 drives this signal only
when TPHY_ADD matches
CFG_ADDR in the UI_SNK_CFG
register in the previous cycle. A
pulldown resistor is recommended.
Any-PHY
: This pin is the Transmit
Packet Available (TPA) signal which
functions the same as TPHY_CLAV
except for it is activated two cycles
after a matching address instead of
one.

ATM
: These signals are not used in
ATM mode.
PHY
: Transmit UTOPIA PHY Layer
Address (Bits 4 to 0) which selects
the UTOPIA transmitter. These
inputs are used as an output enable
for TPHY_CLAV and to validate the
activation of TPHY_ENB. There are
internal pull-up resistors. These
pins are compared with
CFG_ADDR[4:0] in the
UI_SNK_CFG_ADDR register.
ANY-PHY:
Transmit Start
Transfer(TSX) is an active high input
which indicates the start of an Any-
PHY packet which identifies the
location of the prepended address.
ANY-PHY_EN in UI_SNK_CFG
register needs to be set for this
