It features fully vacuum encapsulated construction using materials conforming to UL94V-0 flammability requirements. The part is compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional placement and reflow. P3000 performs the functions of reinforced safety barrier (3750Vrms), telephone line matching and 2-4 wire conversion. This component is designed specifically for high speed full-duplex data transmission where very low levels of distortion are required. High performance is achieved by realizing a very low noise floor at the receive port even when the power sourced at the transmit port is high. Circuit simplification is readily achieved as the transmit, receive and line ports are fully floating and galvanically isolated from each other. P3000 is readily matched to complex reference impedances. The transmit and receive frequency responses are very flat (i.e. negligible 'twist') when matched to complex impedances. For best operation the module requires a transmit drive from a high-quality low-impedance source («10Ω), and a high impedance receive load (47kΩ nominal). These impedances may be directly provided by datapumps. P3000 is also useful for voice applications requiring 2-4 wire conversion as its port impedances are particularly suitable for CODECs. P3000 is certified to IEC 950 and UL 60950. P3000 is a UL Recognized Component, and is supported by an IEC CB Test Certificate.
