ICS342
FIELD PROGRAMMABLE DUAL OUTPUT SS VERSACLOCK SYNTHESIZER
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 CLK2 for each PLL powered up. PDTS transition
high on select address change.
