Data Outputs:
One 10 bit data byte. RX[0] is the first bit received.
RX[0] is the least significant bit.
C
Loop Filter Capacitor:
A loop filter capacitor for the internal PLL must
be connected across the RXCAP0 and RXCAP1 pins. (typical value = 0.1
μ
F).
Data Inputs:
One 10 bit, 8B/10B-encoded data byte. TX[0] is the first
bit transmitted. TX[0] is the least significant bit.

Loop Filter Capacitor:
A loop filter capacitor must be connected across
the TXCAP1 and TXCAP0 pins (typical value = 0.1

Logic Power Supply:
Normally 3.3 volts. Used for internal receiver
PECL logic. It should be isolated from the noisy TTL supply as well as
possible.
Analog Power Supply:
Normally 3.3 volts. Used to provide a clean
supply line for the PLL and high-speed analog cells.
High-Speed Supply:
Normally 3.3 volts. Used only for the high-speed
receiver cell (HS_IN). Noise on this line should be minimized for best
operation.
TTL Power Supply:
Normally 3.3 volts. Used for all TTL receiver output
buffer cells.

Normally 3.3 volts. Used for internal transmitter PECL
logic. It should be isolated from the noisy TTL supply as well as possible.
Analog Power Supply:
Normally 3.3 volts. Used to provide a clean
supply line for the PLL and high-speed analog cells.
High-Speed ECL Supply:
Normally 3.3 volts. Used only for the last stage
of the high-speed transmitter output cell (HS_OUT) as shown in
Figure 10. Due to high current transitions, this V
CC
should be well
bypassed to a ground plane.
High-Speed Supply:
Normally 3.3 volts. Used by the transmitter side for the
high-speed circuitry. Noise on this line should be minimized for best operation.
TTL Power Supply:
Normally 3.3 volts. Used for all TTL
transmitter input buffer cells.
