Features
• Low operating curremt consumption (typical 4 mA)
• High input sensetivity, high input frequencies ( 50 MHz)
• Synchronous programming of the counters (n-, n/a, r-counters)
• Switchable modulus trigger edge
• Large dividing ratios for small channel spacing
   A counter 0 to 127
   N counter 3 to 16,380
   R counter 3 to 65,535
• Serial control:
• 3-wire bus: data, clock (<10 MHz), enable
• Switchable polarity and programmable phase detector current
• 2 programmable outputs
• Digital phase detector output signals (e.g. for external charge pump)
• DRFIN, DVFI outputs (e.g. for prescalar standby)
• External current setting for PD output
• Lock detect outpuut with gated anti-backlash pulse (quasi digital lock detect)
• ESD protection in accordance with MIL-STDs
