DESCRIPTION
PWR Ground pin.
Asynchronous active high input pin used to power down the
IN device. The internal clocks are disabled and the VCO is
stopped.
IN Active high input to stop SRC outputs.
IN
3.3V input for selecting PLL Band Width
0 = High, 1= Low
OUT 0.7V differential complement clock outputs
OUT 0.7V differential true clock outputs
PWR Power supply, nominal 3.3V
PWR Ground pin.
OUT 0.7V differential complement clock outputs
OUT 0.7V differential true clock outputs
IN
Active low input for enabling DIF pair 5.
1 = tri-state outputs, 0 = enable outputs
IN
Active low input for enabling DIF pair 6.
1 = tri-state outputs, 0 = enable outputs
OUT 0.7V differential complement clock outputs
OUT 0.7V differential true clock outputs
PWR Power supply, nominal 3.3V
This latched input selects the polarity of the OE pins.
IN
0 = OE pins active high, 1 = OE pins active low (OE#)
OUT 0.7V differential complement clock outputs
OUT 0.7V differential true clock outputs
IN
Active low input for enabling DIF pair 4
1 = tri-state outputs, 0 = enable outputs
IN
Active low input for enabling DIF pair 7.
1 = tri-state outputs, 0 = enable outputs
OUT
3.3V output indicating PLL Lock Status. This pin goes high
when lock is achieved.
This pin establishes the reference current for the differential
IN
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 PLL core.
PWR 3.3V power for the PLL core.
