SP4653

The SP4653 is designed as the 4256 prescaler that is one of GPS' range of high speed dividers for consumer frequency synthesis and measurement systems. This device has a low supply current, giving reduced dissipation and operating temperatures in an 8-pin plastic DIL (DP8) or miniature plastic DIL (MP8) package. Also this device incorporates an on-chip preamplifier with differential inputs and has a TTL/CMOS compatible output. Features of the SP4653 are:(1)low supply current; (2)low radiation; (3)input wideband amplifier; (4)high input sensitivity; (5)high input impedance; (6)TTL/CMOS output; (7)electrostatic protection.

The absolute maximum ratings of the SP4653 can be summarized as:(1)Supply voltage, Vcc: +7 V;(2)Input voltage: 2·5V p-p;(3)Storage temperature: -55°C to +150°C;(4)Operating temperature range: 0°C to +180°C.
