AC Electrical Characteristics

Unless stated otherwise, VDD = 3.3V ±5%, Ambient Temperature -40 to +85 C

Note 1: Measured with 15 pF load.

Note 2: Duty Cycle is configuration dependent. Most configurations are minimum 45% and maximum 55%.

Note 3: ICS test mode output occurs for first 170 clock cycles on CLK3 for each PLL powered up.
