Pin Function
Differential PECL/ECL Input: Internal 75k pull-down resistor. If left open,
pin defaults LOW. See “Input Interface Applications” section for single-
Differential PECL/ECL Output: Output CLK input divided by 2. See “Output
Interface Applications” section for recommendations on terminations.
Positive Power Supply: Bypass with 0.1 F//0.01 F low ESR capacitors.
Negative Power Supply: V
negative supply. For PECL/LVPECL connect to ground.
Bias Reference Voltage: VCC–1.4V. Used as reference voltage for single-
ended inputs or AC-coupling to the CLK, /CLK inputs. Max sink/source is
Single-ended Input: PECL/ECL Asynchronous reset.
