high frequency prescaler which can be switched off.
5 open collector switching outputs are available.
Features
D 1.3 GHz divide-by-8 prescaler integrated
(can be bypassed)
D 15 bit counter accepts input frequencies up to
170 MHz
D mP-controlled by I
2
C-Bus
D 5 switching outputs (open collector )
D 4 addresses selectable at Pin 8 for multituner
application
D 62.5 kHz (1.3 GHz)/ 7.8125 kHz (170 MHz) tuning
steps
D Electrostatic protection according to MILSTD 883
D SO16 small package
