PWR Power pin for the 3V66 clocks.
PWR Ground pin.
PWR 3.3V Analog Power pin for Core PLL
This pin establishes the reference current for the differential current-mode output pairs. This
pin requires a fixed precision resistor tied to ground in order to establish the appropriate
current. 475 ohms is the standard value.
PWR Ground pin for the CPU outputs
"Complimentary" clocks of differential pair CPU outputs. These are current mode outputs.
External resistors are required for voltage bias.
"True" clocks of differential pair CPU outputs. These are current mode outputs. External
resistors are required for voltage bias.
PWR Supply for CPU clocks, 3.3V nominal
"Complimentary" clocks of differential pair CPU outputs. These are current mode outputs.
External resistors are required for voltage bias.
"True" clocks of differential pair CPU outputs. These are current mode outputs. External
resistors are required for voltage bias.
Asynchronous active low input pin used to power down the device into a low power state. The
internal clocks are disabled and the VCO and the crystal are stopped. The latency of the
power down will not be greater than 1.8ms.
PWR Ground pin for the CPU outputs
"Complimentary" clocks of differential pair CPU outputs. These are current mode outputs.
External resistors are required for voltage bias.
"True" clocks of differential pair CPU outputs. These are current mode outputs. External
resistors are required for voltage bias.
PWR Supply for CPU clocks, 3.3V nominal
PWR Ground pin for the REF outputs.
3.3V LVTTL input for selection the current multiplier for CPU outputs / 14.318 MHz reference
clock.
