Low-Voltage 1:10 Differential ECL/PECL/HSTL Clock Driver
MC100EP111 skew 1-to-10 differential driver, designed with clock distribution mind. accepts clock sources into input multiplexer. ECL/PECL input signals either differential single-ended output used. HSTL inputs used when EP111 operating under PECL conditions. selected signal fanned identical differential outputs. 100ps Part-to-Part Skew typical 35ps Output-to-Output Skew typical Differential Design Output Voltage Range -2.25 -3.8V Voltage Range +2.25 +3.8V PECL HSTL Input Pulldown Resistors ECL/PECL Outputs
MC100EP111
LOW-VOLTAGE 1:10 DIFFERENTIAL ECL/PECL/HSTL CLOCK DRIVER
EP111 specifically designed, modeled produced with skew goal. Optimal design layout serve minimize gate-to-gate skew within device, empirical modeling used determine process control limits that ensure consistent distributions from lot. result dependable, guaranteed skew device. ensure that tight skew specification necessary that both sides differential output terminated into even only side being used. most applications, differential pairs will used therefore terminated. case where fewer than pairs used, necessary terminate least output pairs same package side pair(s) being used that side, order maintain minimum skew. Failure this will result small degradations propagation delay order 10-20ps) output(s) being used which, while being catastrophic most designs, will mean loss skew margin. MC100EP111, with most other devices, operated from positive supply PECL mode. This allows EP111 used high performance clock distribution +3.3V +2.5V systems. Designers take advantage EP111's performance distribute skew clocks across backplane board. PECL environment, series Thevenin line terminations typically used they require additional power supplies. more information using PECL, designers should refer Motorola Application Note AN1406/D. MC100EP111 driven single-endedly utilizing bias output with CLK0 input. single-ended signal used, should connected CLK0 input bypassed ground 0.01 capacitor. output only source/sink 0.2mA; therefore, should used switching reference MC100EP111 only. Part-to-Part Skew specifications guaranteed when driving MC100EP111 single-endedly.
