12
OUT5b
O
LVTTL1
Configurable clock output 5b. Output levels controlled by
VDDO5.
13
VDDO5
Power
Device power supply. Connect to 1.8 to 3.3V. Sets output
voltage levels for OUT5 and OUT5b.
14
GND
Power
Connect to Ground.
15
SDAT
I/O
Open Drain
Bidirectional I2C data. An external pull-up resistor is
required. See I2C specification for pull-up value
recommendation.
16
SCLK
I
LVTTL
I2C clock. An external pull-up resistor is required. See
I2C specification for pull-up value recommendation.
17
CLKSEL
I
LVTTL
Input clock selector. Weak internal pull down resistor.
18
AVDD
Power
Device analog power supply. Connect to 3.3V. Use
filtered analog power supply if available.
19
GND
Power
Connect to Ground.
20
OUT6
O
LVTTL
Configurable clock output 6. Output levels controlled by
VDDO3.
21
OUT3
O
LVTTL
Configurable clock output 3. Output levels controlled by
VDDO3.
22
VDDO3
Power
Device power supply. Connect to 1.8 to 3.3V. Sets output
voltage levels for OUT3 and OUT6.
23
SEL2
I
LVTTL
Configuration select pin. Weak internal pull down
resistor.
24
SEL1
I
LVTTL
Configuration select pin. Weak internal pull down
resistor.
25
SEL0
I
LVTTL
Configuration select pin. Weak internal pull down
resistor.
26
SD/OE
I
LVTTL
Enables/disables the outputs or powers down the chip.
The SP bit (0x02) controls the polarity of the signal to be
either active HIGH or LOW. (Default is active LOW.)
Weak internal pull down resistor.
27
GND
Power
Connect to Ground.
28
VDD
Power
Device power supply. Connect to 3.3V.
1.When only an individual single-ended clock output is required, tie OUT# and OUT#b together.
2. Analog power plane should be isolated from a 3.3V power plane through a ferrite bead.
3. Each power pin should have a dedicated 0.01F de-coupling capacitor. Digital VDDs may be tied together.
4. Unused clock inputs (REFIN or CLKIN) must be pulled high or low - they cannot be left floating. If the crystal oscillator is not used, XOUT must be left floating.
