low skew, 1, 2 lvcmos/ lvttl clock generator w/polariity control ics8701i-01 ics8701ayi-01 revision a march 2, 2010 1 ? 2010 integrated device technology, inc. g eneral d escription the ics8701i-01 is a low skew, 1, 2 lvcmos/ lvttl clock generator. the low impedance lvcmos outputs are designed to drive 50 series or parallel terminated transmission lines. the effective fanout can be increased from 20 to 40 by utilizing the ability of the outputs to drive two series terminated lines. the divide select inputs, div_selx, control the output frequency of each bank. the outputs can be utilized in the 1, 2 or a combi- nation of 1 and 2 modes. the master reset/output enable input, nmr/oe, resets the internal dividers and controls the active and high impedance states of all outputs. the output polarity inputs, inv0:1, control the polarity (inverting or non-inverting) of the out- puts of each bank. outputs qa0:qa4 are inverting for every com- bination of the inv0:1 input. the timing relationship between the inverting and non-inverting outputs at different frequencies is shown in the timing diagrams. the ics8701i-01 is characterized at 3.3v and mixed 3.3v input supply, and 2.5v output supply operating modes. guaranteed bank, output and part-to-part skew characteristics make the ics8701i-01 ideal for those clock distribution applications de- manding well defined performance and repeatability. f eatures ? twenty lvcmos/lvttl outputs, 7 typical output impedance ? one lvcmos/lvttl clock input ? maximum output frequency: 250mhz ? selectable inverting and non-inverting outputs ? bank enable logic allows unused banks to be disabled in reduced fanout applications ? output skew: 300ps (maximum) ? part-to-part skew: 700ps (maximum) ? bank skew: 250ps (maximum) ? multiple frequency skew: 350ps (maximum) ? 3.3v or mixed 3.3v input, 2.5v output operating supply ? -40c to 85c ambient operating temperature ? available in both standard (rohs 5) and lead-free (rohs 6) packages b lock d iagram p in a ssignment hiperclocks? ic s div_sela div_selb div_selc div_seld nmr/oe inv0 inv1 qa0:qa4 qb0:qb4 qc0:qc4 qd0:qd4 clk 1 0 1 2 1 0 1 0 1 0 output polarity control 48 47 46 45 44 43 42 41 40 39 38 37 13 14 15 16 17 18 19 20 21 22 23 24 1 2 3 4 5 6 7 8 9 10 11 12 36 35 34 33 32 31 30 29 28 27 26 25 qc3 v ddoc qc4 qd0 v ddod qd1 gnd qd2 gnd qd3 v ddod qd4 qb1 v ddob qb0 qa4 v ddoa qa3 gnd qa2 gnd qa1 v ddoa qa0 div_sela div_selb clk gnd v dd inv0 gnd inv1 v dd nmr/oe div_selc div_seld gnd qb2 gnd qb3 v ddob qb4 qc0 v ddoc qc1 gnd qc2 gnd 48-pin lqfp 7mm x 7mm x 1.4mm package body y package top view ics8701i-01
