Output Clock Supply Voltage.
Supply voltage (3.3, 2.5, 1.8, or 1.5 V) for CLK2A,B.
A 0.1 µF capacitor must be located very close to this pin. If CLK2 is
not used, this pin must be tied to VDD (pin 7, 24).
Output Clock Supply Voltage.
Supply voltage (3.3, 2.5, 1.8, or 1.5 V) for CLK1A,B.
A 0.1 µF capacitor must be located very close to this pin. If CLK1 is
not used, this pin must be tied to VDD (pin 7, 24).
Output Clock B for Channel 1.
May be a single-ended output or half of a differential output with
CLK1A being the other differential half. If unused, leave this pin
floating.
Output Clock A for Channel 1.
May be a single-ended output or half of a differential output with
CLK1B being the other differential half. If unused, leave this pin
floating.
I
This is the serial data for the I
required. Typical values would be 1–4 k. See the I
for more information. This pin is 3.3 V tolerant regardless of the
other supply voltages on pins 7, 11, 15, 16, 20, 24. See Register
27.
Output Clock Supply Voltage.
Supply voltage (3.3, 2.5, 1.8, or 1.5 V) for CLK0A,B.
A 0.1 µF capacitor must be located very close to this pin. If CLK0 is
not used, this pin must be tied to VDD (pin 7, 24).
Output Clock B for Channel 0.
May be a single-ended output or half of a differential output with
CLK0A being the other differential half. If unused, leave this pin
floating.
Output Clock A for Channel 0.
May be a single-ended output or half of a differential output with
CLK0B being the other differential half. If unused, leave this pin
floating.
Ground.
Must be connected to system ground. Minimize the ground path
impedance for optimal performance of this device.
Core Supply Voltage.
The device operates from a 1.8, 2.5, or 3.3 V supply. A 0.1 µF
bypass capacitor should be located very close to this pin.
Ground Pad.
This is the large pad in the center of the package. Device
specifications cannot be guaranteed unless the ground pad is
properly connected to a ground plane on the PCB. See Table 18,
“PCB Land Pattern,” on page 38 for ground via requirements.
