SDH/SONET STM16/OC48 main ampliers
OQ2538HP; OQ2538U
PINNING
Notes
1. Pin type abbreviations: O = Output, I = Input, S = power Supply and A = Analog function.
2. All GND and VEE pads must be bonded; do not leave one single GND or VEE pad unconnected!
3. Pads denoted ‘n.c.’ should not be connected. Connections to these pads degrade device performance.
