DESCRIPTION
Ground pin for the REF outputs.
Ref, XTAL power supply, nominal 3.3V
Crystal input, nominally 14.318MHz
Crystal output, nominally 14.318MHz
Power pin for the 48MHz outputs and core. 3.3V
48MHz clock output.
48MHz clock output.
Ground pin for the 48MHz outputs
Clock pin of SMBus circuitry, 5V tolerant.
Data pin for SMBus circuitry, 5V tolerant.
Real Time falling edge triggered input, When asserted, the part initiates a power
up reset with the SMBus being reset to it's power up values, and all PLL derived
clocks stopped for the duration of Power up Stabilization. REF outputs continue
to run.
True clock of low power differential SRC clock pair with integrated 33 ohm series
resistor. (no 50ohm shunt resistor to GND needed)
Complement clock of low power differential SRC clock pair with integrated 33
ohm series resistor. (no 50ohm shunt resistor to GND needed)
Supply for SRC, 3.3V nominal
Ground pin for the SRC outputs
True clock of low power differential SRC clock pair with integrated 33 ohm series
resistor. (no 50ohm shunt resistor to GND needed)
Complement clock of low power differential SRC clock pair with integrated 33
ohm series resistor. (no 50ohm shunt resistor to GND needed)

Supply for SRC, 3.3V nominal
Ground pin for the SRC outputs
Programmable Clock Request pin for SRC/ATIG/SB_SRC outputs. If output is
selected for control, then that output is controlled as follows:
0 = Enabled, 1 = Tri-state
