Although the device will function properly for pulse widths as small as 20% of the total delay and periods as small as 40% of the total delay (for a symmetric input), the delays may deviate from their values at low frequency. However, for a given input condition, the deviation will be repeatable from pulse to pulse. Contact technical support at Data Delay Devices if your application requires device testing at a specific input condition. POWER SUPPLY BYPASSING The DDU224F relies on a stable power supply to produce repeatable delays within the stated tolerances. A 0.1uf capacitor from VCC to GND, located as close as possible to the VCC pin, is recommended. A wide VCC trace and a clean ground plane should be used. 10% 10% 10% 10% VCC GND IN T1 T2 T3 T4 T10 Functional diagram for dash numbers < 50 3.5ns 10% 10% 10% 10% T5 T6 T7 T8 10% T9 10% 10% 10% 10% VCC GND IN T1 T2 T3 T4 T10 Functional diagram for dash numbers >= 50 10% 10% 10% 10% T5 T6 T7 T8 10% T9 10% |
