Low Skew, 1-to-12 LVCMOS/LVTTL Clock ICS87973-SC9 Multiplier/Zero Delay Buffer DATA SHEET The ICS87973-SC9 is a LVCMOS/LVTTL clock generator. The ICS87973-SC9 has three selectable inputs and provides 14 LVCMOS/LVTTL outputs. The ICS87973-SC9 is a highly flexible device. The three selectable inputs 1 differential and 2 single ended inputs are often used in systems requiring redundant clock sources. Up to three different output frequencies can be generated among the three output banks. The three output banks and feedback output each have their own output dividers which allows the device to generate a multitude of different bank frequency ratios and output-to-input frequency ratios. In addition, 2 outputs in Bank C QC2, QC3 can be selected to be inverting or non-inverting. The output frequency range is 10MHz to 150MHz. The input frequency range is 6MHz to 120MHz. The ICS87973-SC9 also has a QSYNC output which can be used for system synchronization purposes. It monitors Bank A and Bank C outputs and goes low one period prior to coincident rising edges of Bank A and Bank C clocks. QSYNC then goes high again when the coincident rising edges of Bank A and Bank C occur. This feature is used primarily in applications where Bank A and Bank C are running at different frequencies, and is particularly useful when they are running at non-integer multiples of one another. • Fully integrated PLL • Fourteen LVCMOS/LVTTL outputs to include twelve clocks, one feedback, one sync • Selectable differential CLK, nCLK inputs or LVCMOS/LVTTL reference clock inputs • CLK0, CLK1 can accept the following input levels: LVCMOS or LVTTL • CLK, nCLK pair can accept the following differential input levels LVPECL, LVDS, LVHSTL, SSTL, HCSL • Output frequency range 30MHz to 150MHz • VCO range 240MHz to 500MHz • Output skew 250ps maximum • Cycle-to-cycle jitter, all banks ÷4 55ps maximum • Full 3.3V supply voltage • 0°C to 70°C ambient operating temperature • Available in lead-free RoHS 6 package Pin Assignment GNDO QB0 VDDO QB1 GNDO QB2 VDDO QB3 EXT_FB GNDO QFB VDD FSEL_FB0 39 38 37 36 35 34 33 32 31 30 29 28 27 FSEL_B1 FSEL_B0 FSEL_A1 FSEL_A0 QA3 VDDO QA2 GNDO QA1 VDDO QA0 GNDO VCO_SEL ICS87973-SC9 52-Lead LQFP 45 46 10mm x 10mm x 1.4mm 21 20 package body Y Package Top View 1 2 3 4 5 6 7 8 9 10 11 12 13 FSEL_FB1 QSYNC GNDO QC0 VDDO QC1 FSEL_C0 FSEL_C1 QC2 VDDO QC3 GNDO INV_CLK GNDI nMR/OE FRZ_CLK FRZ_DATA FSEL_FB2 PLL_SEL REF_SEL CLK_SEL CLK0 CLK1 CLK nCLK VDDA 2010 Integrated Device Technology, Inc.
