FEATURES  
DESCRIPTION  
3.3V and 5V power supply options  
Up to 1GHz clock frequencies  
The SY89424V is a low-power Phase Locked Loop  
(PLL) based frequency synthesizer. The device is capable  
of generating up to 1GHz clock frequencies with a low-cost  
10–25MHz external series-resonant quartz crystal. One  
can also use PECL differential clock signals to drive this  
device instead of the quartz crystal. Operation of this chip  
is controlled by three select pins (S1, S2 and S3). S1  
selects the divide ratio of 24 or 50 for the PLL. S2 and S3  
select the output frequency. There are two pull-down  
resistor pins (PDR1 and PDR2). Each pin has an on-chip  
resistor that will control the output driver currents. When  
PDR1 and PDR2 pins are open, both outputs are normal  
open emitter PECL drivers. When PDR1 and PDR2 pins  
are shorted to the outputs, on-chip pull down currents of  
25mA (40mA at 5V VCC) are provided. Both output drivers  
are capable of driving 20 ohm clock lines. An output enable  
(OE) pin is available and it can be HIGH or left open for  
normal operation. When OE is LOW, a built-in Disable  
Timing Synchronizer will force the FOUT output to LOW at  
the completion of the HIGH clock cycle. The FOUT output  
remains HIGH during that time.  
Internal quartz reference oscillator driven by quartz  
crystal or PECL source  
Low jitter PLL design  
On-chip 20 ohm driver  
Differential outputs with 600mV (min) swing  
Optional pull-down resistors for AC-coupled outputs  
Low power consumption  
External loop filter optimizes performance/cost  
Available in 16-pin SOIC package
