Set physical transmit output current.
Pull-down this pin with an 11.8K 1% resistor to ground.
9
VDDA_1.8
P
1.8V analog core power input from VDDCO (Pin 56).
10
RXM2
I/O
Physical receive or transmit signal (– differential)
11
RXP2
I/O
Physical receive or transmit signal (+ differential)
12
AGND
GND
Analog ground.
13
TXM2
I/O
Physical transmit or receive signal (– differential)
14
TXP2
I/O
Physical transmit or receive signal (+ differential)
15
FXSD2
I
MLL/RLL: connect to analog ground by pull-down resistor.
FLL: Fiber signal detect / factory test pin
16
PWRND
Ipu
Chip power down input (active low).
17
X1
I
25MHz or 50MHz crystal/oscillator clock connections.
Pins (X1, X2) connect to a crystal. If an oscillator is used, X1 connects to a 3.3V
tolerant oscillator and X2 is a no connect.
Note: Clock is ± 50ppm for crystal and oscillator, the clock should be applied to X1
pin before reset voltage goes high.
