DESCRIPTION
LATCHED Tri-level latch to select SMBus Address. See SMBus Address Selection Table.
IN
Active low input for enabling DIF pair 6. This pin has an internal pull-down.
IN
1 =disable outputs, 0 = enable outputs
OUT Differential true clock output
OUT Differential Complementary clock output
PWR 1.5V power for differential input clock (receiver). This VDD should be treated as an Analog
power rail and filtered appropriately.
IN True Input for differential reference clock.
IN Complementary Input for differential reference clock.
GND Ground pin for digital circuitry
IN Clock pin of SMBus circuitry, 3.3V tolerant.
I/O Data pin for SMBus circuitry, 3.3V tolerant.
PWR 1.5V digital power (dirty power)
PWR Power supply for differential outputs
IN
Active low input for enabling DIF pair 0. This pin has an internal pull-down.
1 =disable outputs, 0 = enable outputs
OUT Differential true clock output
OUT Differential Complementary clock output
PWR Power supply, nominally 1.5V
PWR Power supply for differential outputs
OUT Differential true clock output
OUT Differential Complementary clock output
N/A No Connection.
IN
Active low input for enabling DIF pair 1. This pin has an internal pull-down.
1 =disable outputs, 0 = enable outputs
OUT Differential true clock output
OUT Differential Complementary clock output
IN
Active low input for enabling DIF pair 2. This pin has an internal pull-down.
1 =disable outputs, 0 = enable outputs
PWR 1.5V power for the PLL core.
PWR Power supply for differential outputs
OUT Differential true clock output
OUT Differential Complementary clock output
IN
Active low input for enabling DIF pair 3. This pin has an internal pull-down.
1 =disable outputs, 0 = enable outputs
N/A No Connection.
PWR Power supply, nominally 1.5V
PWR Power supply for differential outputs
OUT Differential true clock output
OUT Differential Complementary clock output
Active low input for enabling DIF pair 4. This pin has an internal pull-down.
IN
1 =disable outputs, 0 = enable outputs
OUT Differential true clock output
OUT Differential Complementary clock output
IN
Active low input for enabling DIF pair 5. This pin has an internal pull-down.
1 =disable outputs, 0 = enable outputs
PWR Power supply for differential outputs
Input notifies device to sample latched inputs and start up on first high assertion. Low enters
IN Power Down Mode, subsequent high assertions exit Power Down Mode. This pin has internal
pull-up resistor.
GND Connect paddle to ground.
