TB2118F Description
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.
TB2118F Key Features
- Built-in high-speed program divider with built-in prescalers. FM: 30~150MHz (pulse swallowing method) AM: 1~40MHz (pulse
- Phase parator outputs are constant current output for both FM and AM. Current values can be switched using serial data.
- 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
- REG. + 22
