PRELIMINARY INFORMATION  
ICS355  
Triple PLL Quick Turn Clock Synthesizer  
Description  
Features  
• Packaged as 20 pin SSOP (QSOP)  
• Quick turn frequency programming allows  
samples as quickly as one day  
The ICS355 QTClock™ generates up to 9 high  
quality, high frequency clock outputs including a  
reference from a low frequency crystal or clock  
input. It is designed to replace crystals and crystal  
oscillators in most electronic systems. The ICS355  
contains a One Time Programmable (OTP) ROM  
which is factory programmed with PLL divider  
values to output a broad range of frequencies up to  
200 MHz, allowing customer requests for different  
frequencies to be shipped in 1-3 days.  
• Up to 4 outputs can be low-skew  
• Spread-Spectrum capability included  
• Can include 8 selectable output frequencies  
• Up to 5 reference outputs  
• Replaces multiple crystals and oscillators  
• Output frequencies up to 200 MHz at 3.3V  
• Input crystal frequency of 5 - 27 MHz  
• Input clock frequency of 2 - 50 MHz  
• Duty cycle of 45/55  
Programming features include a selectable  
frequency table, up to 4 low-skew outputs, and  
optional Spread Spectrum on PLLA.  
Using Phase-Locked-Loop (PLL) techniques, the  
device runs from a standard fundamental mode,  
inexpensive crystal, or clock. It can replace  
multiple crystals and oscillators, saving board space  
and cost.  
• Operating voltages of 3.3 V or 5 V  
• Advanced, low power CMOS process
