OUTPUTS - TTL
20-bit received character. Parallel data on this bus is clocked out on the rising edge of
RBC(0). R0 is the first bit received on RX+/RX-.

WRAP
Mode. INPUT - TTL
LOW for Normal Operation. When HIGH, an internal loopback path from the
transmitter to the receiver is enabled, TX+ = HIGH and TX- is LOW.
R
eceive Serial Inputs INPUTS - Differential PECL
The receiver inputs when EWRAP is LOW. Internally biased to VDD/2, with 3.3K
resistors to VDD and GND. (AC Coupling recommended)

lock and Complement OUTPUT - TTL
Recovered clock and complement derived from one twentieth of the RX+/- data stream.
The rising edge of RBC(0) corresponds to a new word on R0:19.

DET
ect. INPUT - TTL
Enables comma detection and word resynchronization when HIGH. When LOW, keeps
current word alignment and disables comma detection.
COM

DET
ect OUTPUT - TTL
This output goes HIGH to indicate that R0:6 contains a Comma Character (‘0011111’).
COMDET will go HIGH only during a cycle when RBC(0) is falling. COMDET is
enabled by EN_CDET being HIGH.
T

able INPUT - TTL
When LOW, the TX outputs transmit serial data. When HIGH, the TX+ is HIGH and the
TX- is LOW.
Link
UNUSE
OUTPUT - TTL
Normally is LOW. If R0:19 is all LOW or all HIGH and EWRAP is LOW, this output
will be asserted HIGH to indicate an open link on RX+/-.
