Notes
1. Maximum power dissipation is specified for 96 MHz clock frequency, 45 Msymbols/s and a puncture rate of ⁷⁄₈.
2. Maximum power dissipation is specified for 64 MHz clock frequency, 30 Msymbols/s and a puncture rate of ⁷⁄₈.
HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However it is good practice to take
normal precautions appropriate to handling MOS devices (see “Handling MOS devices”).
