Description
Supply Voltage: Digital supply to gates in analog section, +3.3 Volts ±10%.
Supply Voltage: Digital supply for differential ports, +3.3 Volts ±10%.
Digital Supply for +5 Volts Tolerance to Input Pins. Connect to +5 Volts
(±10%) for clamping to +5 Volts. Connect to VDD for clamping to +3.3
Volts. Leave floating for no clamping, input pins tolerant up to +5.5 Volts.
Supply Voltage: Digital supply to logic, +3.3 Volts ±10%.
Supply Voltage: Analog supply to clock multiplying PLL, +3.3 Volts ±10%.
Supply Voltage: Analog supply to output PLLs, +3.3 Volts ±10%.
Supply Ground: Digital ground for logic
Supply Ground: Digital ground for differential ports.
Supply Ground: Analog grounds.
Note...I = Input, O = Output, P = Power, TTLU = TTL input with pull-up resistor, TTLD = TTL input with pull-down resistor.

Description
JTAG Control Reset Input: TRST = 1 to enable JTAG Boundary Scan mode.
TRST = 0 for Boundary Scan stand-by mode, still allowing correct device
operation. If not used connect to GND or leave floating.
JTAG Test Mode Select: Boundary Scan enable. Sampled on rising edge of
TCK. If not used connect to VDD or leave floating.
