SL38000  
Programmable 4-PLL CG with VCXO and SSCG  
Description  
Key Features  
The SL38000 a fully integrated 4 PLL programmable low  
power Clock Generator with SSCG and VCXO functions  
used for reducing Electromagnetic Interference (EMI) and  
general purpose frequency synthesizing. The product is  
designed using SpectraLinear proprietary programmable  
EProClock™ phase-locked loop (PLL) and Spread  
Spectrum Clock (SSC) technology to synthesize and  
modulate the input clock. The modulated clock can  
significantly reduce the measured EMI levels, and leading  
to the compliance with regulatory agency requirements.  
4 Programmable PLLs with up to 9 Clock Outputs  
and 2 REFCLKs  
Wide 2.5V to 3.3V +/-10% power supply range  
CLKOUTs support 3.3V to 2.5V or 1.8V +/-10%  
Low power dissipation and low jitter  
Programmable VCXO and SSCG options  
EEPROM or I2C Programmability  
Programmable Center or Down Spread Modulation  
from 0.25 to 5.0%  
Up to 9 output clock frequencies and 2 REFOUT clocks,  
Spread %, output rise and fall times for each clock outputs,  
crystal load, modulation frequency and PD#/OE/SSON#/FS  
functions can be programmed to meet the needs of wide  
range of applications. The SL38000 operates from 2.5V to  
3.3V power supply voltage range. The output clocks  
(CLKOUTs) can support 3.3 to 2.5V or 1.8V +/-10%. The  
product is offered in 28-pin TSSOP package with  
commercial and industrial grades.  
8 to 48 MHz external crystal range  
8 to 166 MHz external clock input range  
Programmable 1 to 200 MHz clock output range  
Integrated internal voltage regulator  
Programmable PD#/OE/SSON#/FS functions  
Programmable CL at XIN and XOUT pins  
Programmable output rise and fall times  
28-pin TSSOP package with commercial and  
industrial temperature ranges  
Benefits  
Peak EMI reduction of 8 to 16 dB  
Fast time-to-market  
Cost Reduction  
Reduction of PCB layers  
Eleminates the need for XOs and VCXOs
