Data Outputs: One 10 bit data byte. RX[0] is the first bit received.
RX[0] is the least significant bit.
Loop Filter Capacitor: A loop filter capacitor for the internal PLL must
be connected across the RXCAP0 and RXCAP1 pins. (typical value = 0.1 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 F).
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.
Logic Power Supply: 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
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.
