DDU224F Doc #97015 DATA DELAY DEVICES, INC. 2 1/29/97 Tel: 973-773-2299 Fax: 973-773-9672 http://www.datadelay.com APPLICATION NOTES HIGH FREQUENCY RESPONSE The DDU224F tolerances are guaranteed for input pulse widths and periods greater than those specified in the test conditions. 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% |
