Power supply, nominal 3.3V
0.7 V Differential SRC TRUE input
0.7 V Differential SRC COMPLEMENTARY input
Ground pin.
Power supply, nominal 3.3V
0.7V differential true clock outputs
0.7V differential complement clock outputs
Active high input for enabling outputs.
0 = tri-state outputs, 1= enable outputs
0.7V differential true clock outputs
0.7V differential complement clock outputs
Power supply, nominal 3.3V
Input to select Bypass(fan-out) or PLL (ZDB) mode
0 = Bypass mode, 1= PLL mode
Clock pin of SMBus circuitry, 5V tolerant.
Data pin for SMBus circuitry, 5V tolerant.
Asynchronous active low input pin used to power down the device. The
internal clocks are disabled and the VCO and the crystal are stopped.
Active low input to stop diff outputs.
3.3V input for selecting PLL Band Width
0 = High, 1= Low
Power supply, nominal 3.3V
0.7V differential complement clock outputs
0.7V differential true clock outputs
Active high input for enabling outputs.
0 = tri-state outputs, 1= enable outputs
0.7V differential complement clock outputs
0.7V differential true clock outputs
Power supply, nominal 3.3V
Ground pin.
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.
Ground pin for the PLL core.
3.3V power for the PLL core.
