ICS86953I-147 LOW SKEW, 1-TO-9 DIFFERENTIAL-TO-LVCMOS / LVTTL ZERO DELAY BUFFER GENERAL DESCRIPTION ICS The ICS86953I-147 is a low voltage, low skew 1-to-9 Differential-to-LVCMOS/LVTTL Clock HiPerClockS™ Generator and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS.The PCLK, nPCLK pair can accept most stan- dard differential input levels.With output frequencies up to 175MHz, the ICS86953I-147 is targeted for high performance clock ap- plications. Along with a fully integrated PLL, the ICS86953I-147 contains frequency configurable outputs and an external feed- back input for regenerating clocks with “zero delay”. www.DataSheet4U.com PIN ASSIGNMENT FEATURES • 9 single ended LVCMOS/LVTTL outputs; (8) clocks, (1) feedback • PCLK, nPCLK pair can accept the following differential input levels: LVPECL, CML, SSTL • Maximum output frequency: PLL Mode, 175MHz • VCO range: 250MHz to 700MHz • Output skew: 75ps (maximum) • Cycle-to-cycle jitter: 50ps (maximum) • Static phase offset: 90ps ± 110ps • 3.3V supply voltage • -40°C to 85°C ambient operating temperature • Pin compatible to the MPC953 VDDA FB_CLK nc nc nc nc GND PCLK 32 31 30 29 28 27 26 25 1 24 2 23 3 22 4 ICS86953I-147 21 5 20 6 19 7 18 8 17 9 10 11 12 13 14 15 16 Q1 VDDO Q2 GND Q3 VDDO Q4 GND 32-Lead LQFP 7mm x 7mm x 1.4mm package body Y package Top View BLOCK DIAGRAM PCLK nPCLK FB_CLK VCO_SEL nBYPASS MR/nOE PLL_SEL 86953BYI-147 Phase Detector LPF VCO 0 1 0 ÷2 1 0 ÷4 1 www.icst.com/products/hiperclocks.html 1 QFB /7 Q0:Q6 Q7 REV.
