ICS8735-01 1:5 DIFFERENTIAL-TO-3.3V LVPECL ZERO DELAY CLOCK GENERATOR The ICS8735-01 is a highly versatile 1:5 Differential-to3.3V LVPECL clock generator. The ICS8735-01 has a fully integrated PLL and can be configured as zero delay buffer, multiplier or divider, and has an output frequency range of 31.25MHz to 700MHz. The reference divider, feedback divider and output divider are each programmable, thereby allowing for the following output-to-input frequency ratios 8:1, 4:1, 2:1, 1:1, 1:2, 1:4, The external feedback allows the device to achieve “zero delay” between the input clock and the output clocks. The PLL_SEL pin can be used to bypass the PLL for system test and debug purposes. In bypass mode, the reference clock is routed around the PLL and into the internal output dividers. • Five differential 3.3V LVPECL outputs • Selectable differential clock inputs • CLKx, nCLKx pair can accept the following differential input levels LVPECL, LVDS, LVHSTL, SSTL, HCSL • Output frequency range 31.25MHz to 700MHz • Input frequency range 31.25MHz to 700MHz • VCO range 250MHz to 700MHz • Programmable dividers allow for the following output-to-input frequency ratios 8:1, 4:1, 2:1, 1:1, 1:2, 1:4, 1:8 • External feedback for “zero delay” clock regeneration with configurable frequencies • Cycle-to-cycle jitter 25ps maximum • Output skew 25ps maximum • Static phase offset 50ps ± 100ps • 3.3V supply voltage • 0°C to 70°C ambient operating temperature • Lead-Free fully RoHS compliant BLOCK DIAGRAM PLL_SEL CLK0 nCLK0 CLK1 nCLK1 CLK_SEL FB_IN nFB_IN ÷1, ÷2, ÷4, ÷8, ÷16, ÷32, ÷64 8:1, 4:1, 2:1, 1:1, 1:2, 1:4, 1:8 SEL0 SEL1 SEL2 SEL3 8735AY-01 PIN ASSIGNMENT VCCO nQ4 Q4 VEE SEL3 VCCA PLL_SEL VCC Q0 nQ0 Q1 nQ1 Q2 nQ2 SEL0 32 31 30 29 28 27 26 25 VCCO Q3 nQ3 SEL1 2 CLK0 3 23 Q3 22 nQ3 Q4 nQ4 TABLE ORDERING INFORMATION Part/Order Number 8735AY-01 Marking ICS8735AY-01 Package 32 lead LQFP Shipping Packaging Temperature tray 0°C to 70°C 8735AY-01T ICS8735AY-01 32 lead LQFP 1000 tape & reel 0°C to 70°C 8735AY-01LF ICS8735AY01L 32 lead "Lead Free" LQFP tray 0°C to 70°C 8735AY-01LFT ICS8735AY01L 32 lead "Lead Free" LQFP 1000 tape & reel 0°C to 70°C 8735AK-01 ICS8735AK-01 32 lead VFQFN tray 0°C to 70°C 8735AK-01T ICS8735AK-01 32 lead VFQFN 2500 tape & reel 0°C to 70°C 8735AK-01LF ICS8735A01L 32 lead "Lead Free" VFQFN tray 0°C to 70°C 8735AK-01LFT ICS8735A01L 32 lead "Lead Free" VFQFN 2500 tape & reel 0°C to 70°C NOTE Parts that are ordered with an "LF" suffix to the part number are the Pb-Free configuration and are RoHS compliant. 1 Features Section - added Lead-Free bullet. 16 Ordering Information Table - added Lead-Free part number. 12/22/04 LVPECL DC Characteristics Table -corrected VOH max. from VCCO - 1.0V to VCCO - 0.9V. 4/13/07 11 - 12 Power Considerations - corrected power dissipation to reflect VOH max in Table Updated datasheet's header/footer with IDT from ICS. 16 Ordering Information Table - removed ICS prefix from Part/Order Number column.
