6 / 9 page ICS345 TRIPLE PLL FIELD PROGRAMMABLE SS VERSACLOCK SYNTHESIZER EPROM CLOCK SYNTHESIZER IDT® TRIPLE PLL FIELD PROGRAMMABLE SS VERSACLOCK SYNTHESIZER 6 ICS345 REV P 090613 AC Electrical Characteristics Unless stated otherwise, VDD = 3.3 V ±5%, Ambient Temperature -40 to +85 C Note 1: Measured with 15 pF load. Note 2: Duty Cycle is configuration dependent. Most configurations are min 45% / max 55% Note 3: IDT test mode output occurs for first 170 clock cycles on CLK7 for each PLL powered up. PDTS transition high on select address change. Note 4: The actual ppm error will be displayed in the VersaClock software when the programming file is generated for the customer’s specific configuration. In general, zero ppm error can be achieved, but please note that the device cannot improve upon the error of the input reference clock. For example, if the input crystal has 25 ppm error, then the outputs will also have 25 ppm error. Thermal Characteristics Parameter Symbol Conditions Min. Typ. Max.
