PLL for DTS  
TC9256APG  
The TC9256APG, TC9256AFG, TC9257APG and TC9257AFG  
are phase-locked loop (PLL) LSIs for digital tuning systems (DTS)  
with built-in two-modulus prescalers.  
All functions are controlled through three serial bus lines.  
These LSIs are used to configure high-performance digital  
tuning systems.  
Features  
TC9257APG  
Suitable for use in digital tuning systems in high-fi tuners and  
car stereos.  
Built-in prescalers operate at an input frequency ranging from  
30 to 150 MHz during FM input (with two-modulus  
IN  
prescaler) and at 0.5 to 40 MHz during AM input (with  
IN  
two-modulus prescaler or direct dividing)  
16-bit programmable counter, dual parallel output phase  
comparator, crystal oscillator and reference counter  
3.6 MHz, 4.5 MHz, 7.2 MHz or 10.8 MHz crystal oscillators  
can be used.  
TC9256AFG  
15 possible reference frequencies (when using 4.5 MHz  
crystal):ref. = 0.5 k, 1 k, 2.5 k, 3 k, 3.125 k, 3.90625 k, 5 k, 6.25  
k, 7.8125 k, 9 k, 10 k, 12.5 k, 25 k, 50 k and 100 kHz.  
Built-in 20-bit general-purpose counter for such uses as  
measuring intermediate frequencies (IF  
IN1  
and IF ) and  
IN2  
low-frequency pilot signal cycles (SC ). (No cycle  
IN  
measurement function is available on the TC9256APG and  
TC9256AFG.)  
TC9257AFG  
High-precision (±0.55 to ±7.15 µs) PLL phase error detection  
Numerous general-purpose I/O pins for such uses as  
peripheral circuit control  
Four N-channel open-drain output ports (OFF withstanding  
voltage: 12 V) for such uses as control signal output.  
(TC9256APG and TC9256AFG have only three ports.)  
Standby mode function (turns off FM, AM and IF amps) to  
save current consumption  
All functions controlled through three serial bus lines  
Weight  
CMOS structure with operating power supply range of V  
5.0 ± 0.5 V.
