MDIO
MII Management Interface data TTL input/output. Serial data are written to and read
from the ML6697’s management registers through this I/O pin. Input data is sampled
on the rising edge of MDC. Data output should be sampled synchronously with
MDC's rising edge.
Digital ground.
Digital +5V power supply.
Digital ground.
MII Serial Management Interface address bit 0.
MII Serial Management Interface address bit 1.
MII Serial Management Interface address bit 2.
MII Serial Management Interface address bit 3.
MII Serial Management Interface address bit 4.
Analog +5V power supply.
Analog +5V power supply.
Equalizer bias resistor input. An external 9.53kW, 1% resistor connected between
RGMSET and AGND3 sets internal time constants controlling the receive equalizer
transfer function.
Transmit level bias resistor input. An external 2.49kW, 1% resistor connected between
RTSET and AGND3 sets a precision constant bias current for the twisted pair transmit
level.
Analog ground.
Transmit twisted pair outputs. This differential current output pair drives MLT-3
waveforms into the network coupling transformer.
Analog ground.
Analog +5V power supply.
100BASE-TX link activity open-drain output.
LINK100
pulls low when there is
100BASE-TX activity at TPINP/N in 100BASE-TX or auto-negotiation modes. This
output is capable of driving an LED directly.
Receive twisted pair inputs. This differential input pair receives 100BASE-TX signals
from the network.
Receiver common-mode reference output. This pin provides a common-mode bias
point for the twisted-pair media line receiver, typically (V
CC
– 1.26)V.
Analog +5V power supply.
