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.

DIP-16-300-2.54

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 FMIN input (with 2 modulus prescaler) and

at 0.5~40MHz during AMIN 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 (IFIN1 and IFIN2)

* High-precision (±0.55~±7.15µs) 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.

SOP-16-300-1.27

* Standby mode function (turns off FM, AM

and IF amps) to save current

consumption.

* All functions controlled through 3 serial

bus lines.

* CMOS structure with operating power

supply range of VDD=5.0±0.5V.
