DESCRIPTION

P3000 is a microprofile passive hybrid module for

applications where reinforced insulation is required.

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

(«10

Ω), 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.
