Analog power supply pins.
AGND

Analog power ground pins.
OSCB/REFCLKB
I
Complementary reference clock/oscillator input
(400MHz max.). NOTE: When the REFCLK port is
operated in single-ended mode, then REFCLKB should
be decoupled to AVDD with a 0.1
μ
F capacitor.
Reference clock/oscillator input (400 MHz max.). See
Clock Input section of datasheet for details on the
REFCLK/OSCILLATOR operation.
Output of the oscillator section.
Control pin for the oscillator section. When high, the
oscillator section is enabled. When low, the oscillator
section is bypassed.
This Pin provides the connection for the external zero
compensation network of the REFCLK Multiplier’s PLL
loop filter. The network consists of a 1K ohm resistor in
series with a 0.1
μ
F capacitor tied to AVDD.
Complementary DAC output.
DAC output.
DAC “biasline” decoupling pin.
A resistor (3.85K
nominal) connected from AGND to
DAC_Rset establishes the reference current for the
DAC.
No connect.
Input pin used as an external power down control. See
the External Power Down Control section of this
document for details.
