CM1457: EMI Filter, 4,6 and 8-Channel, with ESD Protection

The CM1457 is an inductor-based (L-C) EMI filter array with ESD protection, which integrates four, six, or eight filters in a CSP form factor with 0.40mm pitch. Each EMI filter channel of the CM1457 is implemented with the component value of 6pF-35nH-4.7pF-35nH-1.8pF. The cut-off frequency at -3dB attenuation is 300MHz and can be used in applications where the data rates are as high as 160Mbps, while providing greater than -35dB attenuation over the 800MHz to 2.7GHz frequency range. The parts include ESD diodes on every I/O pin and provide a high level of protection against electrostatic discharge (ESD). The ESD protection diodes connected to the external filter ports are designed and characterized to safely dissipate ESD strikes of ±15kV, which is beyond the maximum requirement of the IEC61000-4-2 international standard.

特性
  • 700 MHz Attenuation, critical for LTE deployments
  • Chip Scale Package (CSP) features extremely low lead inductance for optimum filter and ESD performance
  • 15kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge)
优势
  • Suppressed EMI assists in improving handset performance in Total Isotropic Sensitivity testing, a requirement to get agency and carrier approvals
  • Space saving benefits from use of 0.4mm pitch CSP
  • Protects against the most agressive ESD events
应用
  • Camera and display interfaces, keypad interfaces
  • Emerging LTE and 4G protocols
终端产品
  • Cellular phones, notebook computers, netbook computers, portable navigation devices
