This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum ratings for extended periods may effect device reliability. SWITCHING SPECIFICATIONS Parameters Symbol AD9243 Units Clock Period 1 tC 333 ns min CLOCK Pulsewidth High tCH 150 ns min CLOCK Pulsewidth Low tCL 150 ns min Output Delay tOD 8 ns min 13 ns typ 19 ns max Pipeline Delay (Latency) 3 Clock Cycles NOTES 1The clock period may be extended to 1 ms without degradation in specified performance @ +25 °C. Specifications subject to change without notice. (TMIN to TMAX with AVDD = +5 V, DVDD = +5 V, DRVDD = +5 V, CL = 20 pF) CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD9243 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. tCL tCH tC tOD DATA 1 DATA OUTPUT INPUT CLOCK ANALOG INPUT S1 S2 S3 S4 Figure 1.
