? semiconductor components industries, llc, 2002 january, 2002 rev. 5 1 publication order number: mc100lvep14/d mc100lvep14 2.5v / 3.3v1:5 differential ecl/pecl/hstl clock driver the mc100lvep14 is a low skew 1to5 differential driver, designed with clock distribution in mind, accepting two clock sources into an input multiplexer. the ecl/pecl input signals can be either differential or singleended (if the v bb output is used). hstl inputs can be used when the lvep14 is operating under pecl conditions. the lvep14 specifically guarantees low outputtooutput skew. optimal design, layout, and processing minimize skew within a device and from device to device. to ensure that the tight skew specification is realized, both sides of any differential output need to be terminated identically into 50 even if only one output is being used. if an output pair is unused, both outputs may be left open (unterminated) without affecting skew. the common enable (en ) is synchronous, outputs are enabled/ disabled in the low state. this avoids a runt clock pulse when the device is enabled/disabled as can happen with an asynchronous control. the internal flip flop is clocked on the falling edge of the input clock; therefore, all associated specification limits are referenced to the negative edge of the clock input. the mc100lvep14, as with most other ecl devices, can be operated from a positive v cc supply in pecl mode. this allows the lvep14 to be used for high performance clock distribution in +3.3 v or +2.5 v systems. single ended clk input pin operation is limited to a v cc 3.0 v in pecl mode, or v ee 3.0 v in necl mode. designers can take advantage of the lvep14's performance to distribute low skew clocks across the backplane or the board. ? 100 ps devicetodevice skew ? 25 ps within device skew ? 400 ps typical propagation delay ? maximum frequency > 2 ghz typical ? the 100 series contains temperature compensation ? pecl and hstl mode: v cc = 2.375 v to 3.8 v with v ee = 0 v ? necl mode: v cc = 0 v with v ee = 2.375 v to 3.8 v ? lvds input compatible ? open input default state http://onsemi.com device package shipping ordering information mc100lvep14dt tssop 75 units/rail mc100lvep14dtr2 tssop 2500 tape & reel tssop20 dt suffix case 948e marking diagram* a = assembly location l = wafer lot y = year w = work week *for additional information, see application note and8002/d 100 vp14 alyw 20 1 1 20
