TTL Power Supply: Normally 5 volts. Used for all TTL receiver output
buffer cells.
Receiver Byte Clocks: The receiver section recovers two 53.125 MHz
receive byte clocks. These two clocks are approximately 180 degrees out
of phase. The receiver parallel data outputs are alternatively clocked on
the rising edge of these clocks. RBC1 aligns and outputs the comma
character (for byte alignment) when detected.
TTL Receiver Ground: Normally 0 volts. Used for the TTL output cells
of the receiver section.
Data Outputs: One 10 bit data byte. RX[0] is the first bit received.
RX[0] is the least significant bit.
Byte Sync Output: An active high output. Used to indicate detection of
either a comma character or a K28.5 special character of positive
disparity. It is only active when ENBYTSYNC is enabled.
Loop Filter Capacitor: A loop filter capacitor for the internal PLL is
connected across the RXCAP0 and RXCAP1 pins.
(typical value = 0.01 F).
Analog Power Supply: Normally 5 volts. Used to provide a clean supply
line for the PLL and high-speed analog cells.
Analog Ground: Normally 0 volts. Used to provide a clean ground
plane for the receiver PLL and high-speed analog cells.
Serial Data Inputs: High-speed inputs. Serial data is accepted from the
High-Speed Supply: Normally 5 volts. Used only for the high-speed
receiver cell (HS_IN). Noise on this line should be minimized for best
operation.
Ground: Normally 0 volts.
High-Speed ECL Supply: Normally 5 volts. Used only for the last stage
of the high-speed transmitter output cell (HS_OUT) as shown in
Figure 9. Due to high current transitions, this V
bypassed to a ground plane.
High-Speed Supply: Normally 5 volts. Used by the transmitter side
for the high-speed circuitry. Noise on this line should be minimized
for best operation.
LOOPEN is set low. When LOOPEN is set high, these outputs are held
static.
Ground: Normally 0 volts.
