TOSHIBA Bi−CMOS Integrated Circuit Silicon Monolithic
TB2118F
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 between FM band edges can be set to approx.
