| AK8146C AK8146C Two Outputs Clock Generator Pin Selectable External Input - 42.72527473MHz - 43.31250000MHz - 27.00MHz - 60.00MHz Clock out Frequencies - 12.000MHz - 13.5MHz Low Jitter Performance - Period Jitter 125 psec max at CLK1 205 psec max at CLK2 Low Current Consumption 5.0mA Typ. at 3.0V Supply Voltage 3.6V Operating Temperature Range -20 to +85℃ Package 8-pin USON Lead free 2.2mm x 2.2mm The AK8146C is a low power multi clock generator which generates different frequency clocks from a external clock input. It provides two outputs of 12MHz and 13.5MHz. PLL in AK8146C are derived from AKEMD’s long-term-experienced clock device technology, and enable clock output to perform low jitter and to operate with very low current consumption. The AK8146C is available in a 8-pin USON package.

These are stress ratings only. Functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Conditions” is not implied. Exposure to absolute-maximum-rating conditions for extended periods may affect device reliability. Electrical parameters are guaranteed only over the recommended operating temperature range. ESD Sensitive Device This device is manufactured on a CMOS process, therefore, generically susceptible to damage by excessive static voltage. Failure to observe proper handling and installation procedures can cause damage. AKEMD recommends that this device is handled with appropriate precautions. Recommended Operation Conditions Parameter Conditions Max Unit Operating temperature Supply voltage 1 Ta VDD Output Load Capacitance Cp1 Pin CLK1,CLK2 Note: 1 Power to VDD requires to be supplied from a single source. A decoupling capacitor of 0.1mF for power supply line should be installed close to each VDD pin. |
