5 / 11 page ![]() MA1916 5/11 DC CHARACTERISTICS AND RATINGS Parameter Min Max Units Supply Voltage -0.5 7 V Input Voltage -0.3 VDD+0.3 V Current Through Any Pin -20 +20 mA Operating Temperature -55 125 °C Storage Temperature -65 150 °C CE_CLK (Convolution Encoder Clock) The CE_CLK input drives the timing of the convolution encoder. Data is read in on CE_IN on the rising edge of CE_CLK and output on CE_OUT on both the rising and falling edge of CE_CLK. Note: The output data rate is twice the input data rate. A 50% duty cycle clock is required. If this is provided by the CLKS output, data can be read directly from RSE_OUT to the CE_IN input (see figure 3). CE_OUT (Convolution Encoder Output) This signal carries the output data from the convolution encoder. The data rate on CE_OUT is twice that of CE_IN. CLK_OUT (Clock Out) CLK_OUT is a buffered output of the CLK input signal. If CLKS is connected to CE_CLK to drive the convolution encoder, CE_OUT can be captured on the falling edge of CLK_OUT. Note: Stresses above those listed may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these conditions, or at any other condition above those indicated in the operations section of this specification, is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
