CIRCUIT DESCRIPTION
Pin 4
Pin 5
Benefits:
• Designed to suppress EMI/RFI Noise in Systems Subjected to
Electromagnetic Interference
• Nominal Cutoff Frequency of 220 MHz (per Figure 2)
• Small Package Size Minimizes Parasitic Inductance, Thus a More
“Ideal” Low Pass Filtering Response

Applications Information
Suppressing Noise at the Source
• Filter all I/O signals leaving the noisy environment
• Locate I/O driver circuits close to the connector
• Use the longest rise/fall times possible for all digital signals
Reducing Noise at the Receiver
• Filter all I/O signals entering the unit
• Locate the I/O filters as close as possible to the connector
Minimizing Noise Coupling
•
•
•
•
•
Use multilayer PCBs to minimize power and ground inductance
Keep clock circuits away from the I/O connector
Ground planes should be used whenever possible
Minimize the loop area for all high speed signals
Provide for adequate power decoupling
ESD Protection
• Locate the suppression devices as close to the I/O connector as possible
• Minimize the PCB trace length to the suppression device
• Minimize the PCB trace length for the ground return for the suppression device
