Key Features
- Non-PLL frequency multiplication by 4.
- Input frequency from 62.5-200 MHz
- Output frequency o PL560-08: 250-600MHz o PL565-08: 600-800MHz
- Low phase noise and jitter (equivalent to fundamental crystal at the output frequency)
- Ultra-low jitter o RMS phase jitter < 100 fs (12kHz-20MHz) o RMS random period jitter < 2 ps
- Low phase noise o -142 dBc/Hz @100kHz offset from the carrier o -150 dBc/Hz @10MHz offset from the carrier
- High linearity pull range (typ. 5%)
- VCXO, set pullability ±100ppm ~ ±200ppm
- Low input frequency eliminates the need for expensive crystals
- Differential output levels: LVPECL
