1GHz464 NON SELF OSCILLATING PRESCALER
3058-2.2
The SP4633 464 prescaler is one of GPS’ range of high speed
dividers for consumer frequency synthesis and measurement
systems. It has a low supply current, giving reduced dissipation
and operating temperatures in an 8-pin plastic DIL package.
Spurious radiation has been reduced from all stages.
The SP4633 incorporates a two-stage preamplifier which
gives good low frequency sensitivity and prevents self-oscillation.
