Test Conditions/Comments

RF CHARACTERISTICS

RF Input Frequency (RFIN)

0.5

GHz

−10 dBm min to 0 dBm max; for lower

frequencies, ensure a slew rate ≥ 400 V/µs

Prescaler Output Frequency

GHz

For higher frequencies, use 8/9 prescaler

REFERENCE CHARACTERISTICS

REFIN Input Frequency

260

MHz

−5 dBm min to +9 dBm max biased at

1.8/2 (ac coupling ensures 1.8/2 bias); for

frequencies < 10 MHz, use a dc-coupled,

CMOS-compatible square wave with a

slew rate > 25 V/µs
