The transmit pad ground (TXVSS) is the return path for
the TXC and TXD+/- outputs. TXVSS is physically
isolated from the other device ground pins and should
be clean to minimize the noise coupled into the
transmit stream.
The power (TAVD1) pin for the transmit clock
synthesizer reference circuitry. TAVD1 should be
connected to a clean, well decoupled, +5V supply.
The ground (TAVS1) pin for the transmit clock
synthesizer reference circuitry. TAVS1 should be
connected to a clean ground reference.
The power (TAVD2) pin for the transmit clock
synthesizer oscillator. TAVD2 should be connected to a
clean, well decoupled, +5V supply.
The ground (TAVS2) pin for the transmit clock
synthesizer oscillator. TAVS2 should be connected to a
clean ground reference.
The power (TAVD3) pin for the transmit reference clock
(TRCLK+/-) inputs. TAVD3 should be connected to a
clean, well decoupled, +5V supply.
The ground (TAVS3) pin for the transmit reference
clock (TRCLK+/-) inputs. TAVS3 should be connected
to a clean ground reference.
The power (RAVD1) pin for receive clock and data
recovery block reference circuitry. RAVD1 should be
connected to a clean, well decoupled, +5V supply.
The ground (RAVS1) pin for receive clock and data
recovery block reference circuitry. RAVS1 should be
connected to a clean ground reference.
The power (RAVD2) pin for receive clock and data
recovery block active loop filter and oscillator. RAVD2
should be connected to a clean, well decoupled, +5V
supply.
The ground (RAVS2) pin for receive clock and data
recovery block active loop filter and oscillator. RAVS2
should be connected to a clean ground reference.
