DESCRIPTION

P5056 is intended for low cost V.90 and V.92

(56kbps)

modems

and

other

high-speed

applications where low distortion at moderate

power levels and very low voiceband frequencies is

required.

P5056 uses patented design and construction

methods to achieve excellent signal performance

and safety isolation to international standards. The

part is completely lead-free, compliant with RoHS

Directive 2002/97/EC, and suitable for lead-free

and conventional processing.

P5056 has exceptionally flat frequency response

from 30Hz to 10kHz, a 3dB bandwidth of 60kHz

and requires only the very simplest of matching to

achieve good return loss and transhybrid loss

across the voiceband, with very low levels of signal

distortion at signal frequencies as low as 150Hz.

P5056 also exhibits stable characteristics over its

full operating temperature range to maximize

data throughput under varying environmental

conditions

without

the

need

for

modem

retraining.

P5056 is certified to IEC 60950 and UL 60950.

P5056 is a UL Recognized Component and is

supported by an IEC CB certificate.
