POWER SUPPLY SENSITIVITY

Figure 6 shows the output frequency sensitivity to power

supply voltage at several different temperatures. The

LTC6902 has a guaranteed voltage coefficient of 0.1%/V

but, as Figure 6 shows, the typical supply sensitivity is

twice as low.

START-UP TIME

The start-up time and settling time to within 1% of the final

10

independent from the setting of the divider pin. For in-

of its 200kHz final value (N = 10) in approximately 380

µs.

Jitter

The Peak-to-Peak Jitter vs Output Frequency graph, in the

Typical Performance Characteristics section, shows the

typical clock jitter as a function of oscillator frequency and

power supply voltage. The capacitance from the SET pin,

(Pin 3), to ground must be less than 10pF. If this require-

ment is not met, the jitter will increase.
