The unique feature of differential CMOS outputs allows great flexibility for board designers. By standardizing on one termination scheme you can use the ABPX1130 for all your LVDS and PECL clock requirements up to 375MHz. +3.3V CMOS Output R1 50 line R2 Input R3 Complementary CMOS Output R1 50 line 3.3V 0V R3 R2 +3.3V Complementary Input PECL LVDS 2.35V 1.40V 1.59V 1.10V Component selection For PECL input For LVDS input Notes: Place R1 as close to the CMOS outputs as possible.
