TXVSS

Ground

128

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.

TAVD1

Power

115

The power (TAVD1) pin for the transmit clock

synthesizer reference circuitry. TAVD1 should be

connected to a clean, well decoupled, +5V supply.

TAVS1

Ground

116

The ground (TAVS1) pin for the transmit clock

synthesizer reference circuitry. TAVS1 should be

connected to a clean ground reference.

TAVD2

Power

117

The power (TAVD2) pin for the transmit clock

synthesizer oscillator. TAVD2 should be connected to a

clean, well decoupled, +5V supply.

TAVS2

Ground

118

The ground (TAVS2) pin for the transmit clock

synthesizer oscillator. TAVS2 should be connected to a

clean ground reference.

TAVD3

Power

119

The power (TAVD3) pin for the transmit reference clock

(TRCLK+/-) inputs. TAVD3 should be connected to a

clean, well decoupled, +5V supply.

TAVS3

Ground

122

The ground (TAVS3) pin for the transmit reference

clock (TRCLK+/-) inputs. TAVS3 should be connected

to a clean ground reference.

RAVD1

Power

145

The power (RAVD1) pin for receive clock and data

recovery block reference circuitry. RAVD1 should be

connected to a clean, well decoupled, +5V supply.

RAVS1

Ground

151

The ground (RAVS1) pin for receive clock and data

recovery block reference circuitry. RAVS1 should be

connected to a clean ground reference.

RAVD2

Power

150

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.

RAVS2

Ground

146

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.
