FUNCTION
Analog Ground
Crystal Connection or Clock Input. If using a 25MHz crystal, connect it to X1 and X2. If using a reference
clock, connect the clock signal to X1 and leave X2 floating. See the
Typical Operating Circuit
.
Power-Supply Input for Analog Circuits. Bypass to GNDA with a 0.1μF capacitor.
Power-Supply Input for Digital Circuits. Bypass to GND with a 0.1μF capacitor.
Serial Clock Input. Serial interface clock.
Serial Data I/O. Data I/O of serial interface.
Digital Ground
Clock 1 Output. Buffered reference clock output.
Clock 2 Output. Frequency-selectable clock output.
Clock 3 Output. Frequency-selectable clock output.
Clock 4 Output. Frequency-selectable clock output.
Clock 5 Output. Frequency-selectable clock output.
Clock 6 Output. Frequency-selectable clock output.

SSC
Spread-Spectrum-Select Input. Selects the spectrum-spread percentage. When SSC is low, spread
spectrum is disabled. When SSC is floating, spread spectrum is set to -1.25%. When SSC is high, spread
spectrum is set to -2.5%.

GND
Address-Select Inputs for Serial Interface. SA0 and SA1 select the serial interface address, as shown in
Table 1. SA0 and SA1 are three-level inputs, making nine possible address combinations.
Exposed pad. Connect to GND.
