Description
Transmit Data. These five outputs are 5B encoded transmit data sym
bols, driven at the rising edge of LSCLK.
TDAT4 is the Most Significant Bit.
LSCLK
I,
TTL
Local Synchrnous Clock. This pin supplies the frequency reference to
the MX98745 within same HUB. It should be driven by a crystal-
controlled 25M clock source.
Receive Data. These 5 bit parallel data symbol from transceiver are
latched by the rising edge of RSCLK of each port.
RDAT4 is the Most Significant Bit.

RDAT[7:1][0:4]
I,
TTL
RSCLK[7:0]
I,
TTL
Recovered Symbol Clock. This is a 25 MHz clock, which is derived
from the clock synchronization PLL circuit.
SIGDET[7:1]
I,
TTL
Signal Detect. This signal indicates that the received signal is above
the detection threshold and will be used for the link test state machine.
Monitor
I,
TTL
Monitor Mode. Internal Pulldown. When this pin is set to one, LED
display pins LED[9:0] will be changed to monitor mode.
