CHAPTER 2 PIN FUNCTIONS
Table 2-1. Receive Interface Signals (2/2)
I/O
O Multi-PHY select address of receive interface 2.
RXADDR23 is the MSB.
I Cell data input of receive interface 2.
Cell data is input from a PHY layer device in byte units. The
µ PD98410 reads the data at the rising edge of UCLK2.
RXDATA27 is the MSB.
I Cell transfer start signal of receive interface 2.
This signal is input from a PHY layer device in synchronization with
the first byte of cell data.
O Transfer enable signal of receive interface 2.
This signal informs a PHY layer device that the µ PD98410 is ready
for reception in the next clock cycle.
I Cell transfer enable signal of receive interface 2.
This pin inputs a signal that indicates that no more cells will be
supplied to the µ PD98410 after the current cell has been
transferred.
I UTOPIA clock input of receive interface 2.
Data is transferred/received in synchronization with the rising edge
of this clock.
O Multi-PHY select address of receive interface 3.
RXADDR33 is the MSB.
I Cell data input of receive interface 3.
Cell data is input from a PHY layer device in byte units. The
µ PD98410 reads the data at the rising edge of UCLK3.
RXDATA37 is the MSB.
I Cell transfer start signal of receive interface 3.
This signal is input from a PHY layer device in synchronization with
the first byte of cell data.
O Transfer enable signal of receive interface 3.
This signal informs a PHY layer device that the µ PD98410 is ready
for reception in the next clock cycle.
I Cell transfer enable signal of receive interface 3.
This pin inputs a signal that indicates that no more cells will be
supplied to the µ PD98410 after the current cell has been
transferred.
I UTOPIA clock input of receive interface 3.
Data is transferred/received in synchronization with the rising edge
of this clock.
