TB2118F
TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic
TB2118F
High Speed PLL For DTS
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. 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. Pins 1 and 24 are susceptible to surge. Take care when handling.

Crystal oscillator output pin
Setting the OSC bit outputs the oscillation frequency. 0 = output off 1 = output on Serial data input: When AM / FM bit = "0" FMVCO is selected. Input signal is directly transferred to the swallow counter. Input frequency: 30 to 150MHz Divided frequency: 528 to 65.535 Serial data input: When AM / FM bit = "1" AMVCO is selected. When mode = "1" AM band is selected (by pulse swallow). Input frequency: 1.0 to 40MHz Divided frequency: 528 to 65.535 input frequency: 0.1 to 15MHz The selected signal is input to a 20-bit general-purpose counter via a gate circuit. Serial interface pins. Data used for controlling TB2118F are exchanged between controllers. Control data are input via DIN in sync. With clock input via CK. Control data input start / stop is specified using CE. General-purpose counter data are output in sync. With clock input via CK from DOUT. The CK / CE / DIN pin is schmitt trigger input.

CMOS power pins Power pins for digital block (digital circuits).

Insert about 10F (as high as possible) between this pin and A-GND. Input from the plus terminal of the op-amp is internally biased to 2.5V.
