PLL FOR DTS
DESCRIPTION
The SC9256 is phase-locked loop (PLL) LSIs for digital tuning
systems (DTS) with built in 2 modulus prescalers.
All functions ate controlled through 3 serial bus lines. These LSIs
are used to configure high-performance digital tuning system.
FEATURES
* Optimal for configuring digital tuning systems in high-fi tuners
and car stereos.
* built-in prescalers. Operate at input frequency ranging from
30~150 MHz during FM
IN
input (with 2 modulus prescaler) and
at 0.5~40MHz during AM
IN
input (with 2 modulus prescaler or
direct dividing).
* 16 bit programmable counter, dual parallel output phase
comparator, crystal oscillator and reference counter.
* 3.6MHz, 4.5MHz, 7.2MHz or 10.8MHz crystal oscillators can be
used.
* 15 possible reference frequencies. ( When using 4.5MHz crystal)
* Built-in 20 bit general-purpose counter for such uses as
measuring intermediate frequencies (IF
IN1
and IF
IN2
)
* High-precision (

s) PLL phase error detection.
* Numerous general-purpose I/O pins for such uses as peripheral
circuit control.
* 3 N-channel open-drain output ports (OFF withstanding
voltage:12V) for such uses as control signal output.
