700MHZ, CYRSTAL-TO-3.3V DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER ICS8432-51 The ICS8432-51 is a general purpose, dual output Crystal-to-3.3V Differential LVPECL High Fre- HiPerClockS q u e n c y S y n t h e s i ze r a n d a m e m b e r o f t h e HiPerClockS family of High Performance Clock Solutions from IDT. The ICS8432-51 has a select- able REF_CLK or crystal input. The VCO operates at a fre- quency range of 250MHz to 700MHz. The VCO frequency is programmed in steps equal to the value of the input reference or crystal frequency. The VCO and output frequency can be programmed using the serial or parallel interface to the con- figuration logic. The low phase noise characteristics of the ICS8432-51 make it an ideal clock source for Gigabit Ethernet, Fibre Channel 1 and 2, and Infiniband applications. • Dual differential 3.3V LVPECL outputs • Selectable crystal oscillator interface or LVCMOS/LVTTL REF_CLK • Output frequency range 31.25MHz to 700MHz • Crystal input frequency range 12MHz to 25MHz • VCO range 250MHz to 700MHz • Parallel or serial interface for programming counter and output dividers • RMS period jitter 3.5ps maximum • Cycle-to-cycle jitter 25ps maximum • 3.3V supply voltage • 0°C to 70°C ambient operating temperature • Available in both standard RoHS 5 and lead-free RoHS 6 packages • Replaces the ICS8432-01 BLOCK DIAGRAM PIN ASSIGNMENT XTAL_IN nP_LOAD VCO_SEL M0 M1 M2 M3 M4 VCO_SEL XTAL_SEL REF_CLK XTAL1 XTAL2 S_LOAD S_DATA S_CLOCK nP_LOAD M0:M8 N0:N1 PLL PHASE DETECTOR CONFIGURATION INTERFACE LOGIC IDT / ICS 3.3V LVPECL FREQUENCY SYNTHESIZER FOUT0 nFOUT0 FOUT1 nFOUT1 TEST 32 31 30 29 28 27 26 25 M5 1 M6 2 M7 3 M8 4 N0 5 N1 6 nc 7 VEE 8 ICS8432-51 24 XTAL_OUT 23 REF_CLK 22 XTAL_SEL 21 VCCA 20 S_LOAD 19 S_DATA 18 S_CLOCK 17 MR TABLE ORDERING INFORMATION Part/Order Number Marking Package Shipping Packaging Temperature ICS8432BY-51 ICS8432BY-51 32 Lead LQFP tray 0°C to 70°C ICS8432BY-51T ICS8432BY-51 32 Lead LQFP 1000 tape & reel 0°C to 70°C ICS8432BY-51LF ICS8432BY51L 32 Lead "Lead-Free" LQFP tray 0°C to 70°C ICS8432BY-51LFT ICS8432BY51L 32 Lead "Lead-Free" LQFP 1000 tape & reel 0°C to 70°C ICS8432BK-51 ICS8432BK51 32 Lead VFQFN tray 0°C to 70°C ICS8432BK-51T ICS8432BK51 32 Lead VFQFN 2500 tape & reel 0°C to 70°C ICS8432BK-51LF ICS8432B51L 32 Lead VFQFN tray 0°C to 70°C ICS8432BK-51LFT ICS8432B51L 11 Crystal section, corrected pin 24 to read XTAL2 and pin 25 to read XTAL1. 1 Features Section - added Lead-Free bullet. 16 Ordering Information - added Lead-Free part number. 1 Added 32 Lead VFQFN Package for Pin Assignment.
