ATM Transmitter/Receiver with UTOPIA Interface
1.0 Product Description
1.10 Pin Definitions
1.10 Pin Definitions
Figure 1-12 is a pinout diagram for the 160-pin ATM Transmitter/Receiver.
Table 1-2 lists pin names and numbers. Generally, all unused input pins should be
connected to ground and unused outputs should be left unconnected. However, if
pins TXOVH_7 to TXOVH_0 or RXIN_8 to RXIN_0 are not used, they must be
tied to a logic low level. Some of the RXIN pins may be used depending on the
configuration. If PECL inputs, RXCKI_HS±, RXIN_HS±, or TXCKI_HS±, are
not used, they must be tied to +5 V power.
