Product Details

Description



Features:

`Builtin highspeed program divider with builtin prescalers.
   FM: 30~150MHz (pulse swallowing method)
   AM: 1~40MHz (pulse swallowing method) 
`Phase comparator outputs are constant current output for both FM and AM. Current values can be switched
   using serial data. In highspeed mode for large current output seek, the lockup time between FM band edges
   can be set to approx. 500s by selecting an appropriate VT range and lopass filter constant. 
`RDS supported 
   Nvalue data and charge pump output current data (total of 18bits) can be selected using two resisters. 
`Builtin lowpass filter opamps for FM and AM. 
`Builtin 20bit binary counter for counting IF frequency. 
`Crystal oscillator can be used 10.25MHz or 10.35MHz. 
`Two output ports (opencollector output) and two I / O ports (CMOS) supported.
Package is SSOP 24 pin.
