CPC1465 SHDSL / ISDN DC Termination ICs
The CPC1465 provides a polarity-insensitive DC termination
for wetting (sealing) current on the CPE side conforming to ITU-
T G.991.2 to eliminate corrosion on SHDSL/ISDN lines. The
CPC1465 has excellent linearity (70dB typ.) to minimize
harmonic distortion and well-controlled turn-on and turn-off
characteristics to minimize injecting impulse noise with in band
signal energy into the channel.
Features
• Meets wetting (sealing) current requirements per
• Integrated bridge rectifier for polarity correction
• Uses inexpensive optocoupler for DC signaling
• Electronic inductor, breakover, and latch circuits
• Current limiting and excess power protection circuits
• ANSI SHDSL and ISDN compatible
• MLT and SARTS compatible
• Excellent linearity (70dB typ.)

This DC termination IC, which interfaces with the tip/ring pair,
is rated at 300V and is able to handle power cross and lightning
transients with appropriate protection. Manufactured in Clare’s
proven 320V Silicon On Insulator (SOI) process, the CPC1465
is packaged in a 16-pin SOIC or DFN.
