TX+, TX-
OUTPUTS - Differential PECL (AC-coupling recommended):
These pins output the serialized transmit data when EWRAP is LOW. When EWRAP is
HIGH, TX+ is HIGH and TX- is LOW.
OUTPUTS - TTL:
10-bit received character. Parallel data on this bus is clocked out on the rising edges of
RCLK and RCLKN. R0 is the first bit received on RX+/RX-.
INPUT - TTL:
LOW for normal operation. When HIGH, an internal loopback path from the transmitter to
the receiver is enabled. TX+ is held HIGH and TX- is held LOW.
INPUTS - Differential PECL (AC-coupling recommended):
The serial receive data inputs selected when EWRAP is LOW. Internally biased to VDD/2,
with 3.3K
resistors from each input pin to VDD and GND.
OUTPUT - Complementary TTL:
Recovered clocks derived from 1/20
th
of the RX+/- data stream. Each rising transition of
RCLK or RCLKN corresponds to a new word on R(0:9).
INPUT - TTL:
Enables COMDET and word resynchronization when HIGH. When LOW, keeps current
word alignment and disables COMDET.
OUTPUT - TTL:
This output goes HIGH for half of an RCLK period to indicate that R(0:9) contains a comma
character (
‘
0011111XXX
’
). COMDET will go HIGH only during a cycle when RCLKN is
rising. COMDET is enabled by ENCDET being HIGH.
OUTPUT - TTL
SIGnal DETect. This output goes HIGH when the RX input contains a valid Fibre Channel or
Gigabit Ethernet signal. A LOW indicates an invalid signal.

INPUT - TTL: JTAG clock input. Not normally connected.
INPUT - TTL: JTAG data input. Not normally connected.
INPUT - TTL: JTAG mode select input. Normally tied to V
