Description
Supply Voltage: Digital supply to gates in analog section, +3.3 Volts
±10%.
Supply Voltage: Digital supply for differential output pins 19 and 20,
+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 APLL2 and APPL1,
+3.3 Volts ±10%.
Supply Ground: Analog ground for output PLLs APLL2 and APPL1.
Supply Ground: Digital ground for components in PLLs.
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.
