Product Details

Description



Features:

• Built−in high−speed program divider with built−in 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 high−speed 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 low−pass filter constant.
• RDS supported
   N−value data and charge pump output current data (total of 18−bits) can be selected using two resisters.
• Built−in low−pass filter op−amps for FM and AM.
• Built−in 20−bit binary counter for counting IF frequency.
• Crystal oscillator can be used 10.25MHz or 10.35MHz.
• Two output ports (open−collector output) and two I / O ports (CMOS) supported.
• Package is SSOP 24 pin.
(Note) Pins 1 and 24 are susceptible to surge. Take care when handling.
