High Speed PLL For DTS
TB2118F
TB2118F is a high−speed phase−locked loop (PLL) LSI for car audio tuners with a built−in charge pump circuit.
All functions are controlled through serial bus lines.
The device is used to configure high−performance digital tuning systems.
Features
· Built−in high−speed program divider with built−in prescalers.
FM: 30~150MHz (pulse swallowing method) AM: 1~40MHz (pulse swallowing method)
Weight: 0.
31g (typ.
)
· 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 ...
