DATA SHEET The ICS84314 is a general purpose quad output frequency synthesizer and a member of the HiPerClockS family of High Performance Clock Solutions from ICS. When the device uses par- allel loading, the M bits are programmable and the output divider is hard-wired for divide by 2 thus providing a frequency range of 125MHz to 350MHz. In serial program- ming mode, the M bits are programmable and the output di- vider can be set for either divide by 2 or divide by 4, providing a frequency range of 62.5MHz to 350MHz. The low cycle- cycle jitter and broad frequency range of the ICS84314 make it an ideal clock generator for a variety of demanding applica- tions which require high performance. • Fully integrated PLL • 4 differential 3.3V or 2.5V LVPECL outputs • Selectable crystal oscillator interface or LVCMOS TEST_CLK input • Output frequency range 62.5MHz to 350MHz • VCO range 250MHz to 700MHz • Parallel interface for programming counter and output dividers during power-up • Serial 3 wire interface • Cycle-to-cycle jitter 23ps typical • Output skew 16ps typical • Output duty cycle 49% < odc < 51%, fout 125MHz • Full 3.3V or mixed 3.3V core, 2.5V operating supply • 0°C to 85°C ambient operating temperature • Lead-Free package available BLOCK DIAGRAM PIN ASSIGNMENT XTAL1 XTAL2 nP_LOAD VCO_SEL VCO_SEL XTAL_SEL TEST_CLK XTAL1 XTAL2 ÷ 16 S_LOAD S_DATA S_CLOCK nP_LOAD M0:M8 PLL PHASE DETECTOR ÷4 1 CONFIGURATION INTERFACE LOGIC 32 31 30 29 28 27 26 25 24 TEST_CLK 23 XTAL_SEL 2 VCCA M7 4 M8 5 ICS84314 21 S_LOAD 20 S_DATA VEE 6 19 S_CLOCK VCC 7 18 MR TABLE ORDERING INFORMATION Part/Order Number ICS84314AY ICS84314AYT ICS84314AYLF Marking ICS84314AY ICS84314AYLF ICS84314AYLFT ICS84314AYLF Package 32 Lead LQFP 32 Lead LQFP on Tape and Reel 32 Lead "Lead-Free" LQFP 32 Lead "Lead-Free" LQFP on Tape and Reel Count 250 per tray 1000 250 per tray 1000 Temperature 0°C to 85°C 0°C to 85°C 0°C to 85°C 0°C to 85°C The aforementioned trademark, HiPerClockS is a trademark of Integrated Circuit Systems, Inc. or its subsidiaries in the United States and/or other countries.
