PECL INPUT OSCAR™ USER CONFIGURABLE CLOCK
Pin Descriptions
Output Clock Selection
If RES is connected directly to ground, CLK1 and CLK2 are low skew, CMOS outputs clocks. They are not
complementary. If RES is connected to VDD through a 1.1 k resistor, then CLK1 and CLK2 become
complementary PECL outputs which require the external resistor network shown in the the block diagram. Refer to
Application Note MAN09 for additional information.
