Description
3.3 V Analog (DAC) Power Supply.
1.8 V Analog (DAC) Power Supply.
Clock Distribution Input. In standard operating mode, this pin is connected to the
filtered DACOUTN output. This internally biased input is typically ac-coupled and,
when configured as such, can accept any differential signal whose single-ended
swing is at least 400 mV.
Clock Distribution Input. In standard operating mode, this pin is connected to the
filtered DACOUTP output
1.8 V Analog (Input Receiver) Power Supply.
Connect an optional 3.12 kΩ resistor from this pin to ground (see the Output
Current Control with an External Resistor section).
Analog Supply for Output Driver. These pins are normally 3.3 V but can be 1.8 V.
Pin 31 powers Out0x. Pin 37 powers OUT1x. Pin 38 powers OUT2x. Pin 44 powers
OUT3x. Apply power to these pins even if the corresponding outputs (OUT0P/
OUT0N, OUT1P/ OUT1N, OUT2P/ OUT2N, and OUT3P/ OUT3N) are not used. See
the Power Supply Partitions section.
Output 0. This output can be configured as LVPECL, LVDS, or single-ended CMOS.
LVPECL and LVDS operation require a 3.3 V output driver power supply. CMOS
operation can be either 1.8 V or 3.3 V, depending on the output driver power
supply.
Complementary Output 0. This output can be configured as LVPECL, LVDS, or
single-ended CMOS.
1.8 V Analog (Output Divider) Power Supply.
Output 1. This output can be configured as LVPECL, LVDS, or single-ended CMOS.
LVPECL and LVDS operation require a 3.3 V output driver power supply. CMOS
operation can be either 1.8 V or 3.3 V, depending on the output driver power
supply.
Complementary Output 1. This output can be configured as LVPECL, LVDS, or
single-ended CMOS.
Output 2. This output can be configured as LVPECL, LVDS, or single-ended CMOS.
LVPECL and LVDS operation require a 3.3 V output driver power supply. CMOS
operation can be either 1.8 V or 3.3 V, depending on the output driver power
supply.
Complementary Output 2. This output can be configured as LVPECL, LVDS, or
single-ended CMOS.
Output 3. This output can be configured as LVPECL, LVDS, or single-ended CMOS.
LVPECL and LVDS operation require a 3.3 V output driver power supply. CMOS
operation can be either 1.8 V or 3.3 V, depending on the output driver power
supply.
Complementary Output 3. This output can be configured as LVPECL, LVDS, or
single-ended CMOS.
3.3 V Analog (System Clock) Power Supply.
System Clock Loop Filter Voltage Regulator. Connect a 0.1 μF capacitor from this
pin to ground. This pin is also the ac ground reference for the integrated SYSCLK
PLL multiplier’s external loop filter (see the SYSCLK PLL Multiplier section).
System Clock Multiplier Loop Filter. When using the frequency multiplier to drive
the system clock, an external loop filter can be attached to this pin.
1.8 V Analog (System Clock) Power Supply.
Complementary System Clock Input. Complementary signal to SYSCLKP. SYSCLKN
contains internal dc biasing and should be ac-coupled with a 0.01 μF capacitor,
except when using a crystal, in which case connect the crystal across SYSCLKP
and SYSCLKN.
