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 output
0.7V differential complement clock output
Active low input for enabling DIF pair 1.
1 = tri-state outputs, 0 = enable outputs
0.7V differential true clock output
0.7V differential complement clock output
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 high input pin used to power down the
device. The internal clocks are disabled and the VCO is stopped.
Active high input to stop SRC outputs.
3.3V input for selecting PLL Band Width
0 = High, 1= Low
Power supply, nominal 3.3V
0.7V differential complement clock output
0.7V differential true clock output
Active low input for enabling DIF pair 6.
1 = tri-state outputs, 0 = enable outputs
0.7V differential complement clock output
0.7V differential true clock output
Power supply, nominal 3.3V
This latched input selects the polarity of the OE pins.
0 = OE pins active high, 1 = OE pins active low (OE#)
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.
