The PEF 22827 modem-on-chip is a single port
integrated QAM based VDSL transceiver, whose
technology complies fully with all current standards for
VDSL - including ITU-T and ETSI.
This IC integrates the following components:
•
•
•
The VDSL digital transceiver is single port standard compliant QAM based VDSL.
The IC can be operated in Central Office (CO) or in the Customer Premises Equipment
(CPE) applications.
The analog front end supports symmetric data rates up to 50 Mbits/s and asymmetric
data rates of 40 Mbits/s upstream and 70 Mbits/s downstream.
The adaptive hybrid connected externally to the analog front end helps improve
transceiver sensitivity and impedance matching to the line, which in turn contribute to a
better data rate and reach performance.
The internal line driver helps implement a simplified design. The line driver consists of
two wide-band amplifiers with a wide dynamic range, implementing one differential line
driver.
The VDSL6100i internal line driver operates on 7 V supplies, generating a differential
output signal of 22 V
QAM line code. A low Total Harmonic Distortion of -55 dB at 10 MHz (V
