Suggested PbF Solder
There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper,
(Sn+Ag+Cu), you can also use Tin and Copper, (Sn+Cu), or Tin, Zinc, and Bismuth, (Sn+Zn+Bi). Please check the manufac
turer's specific instructions for the melting points of their products and any precautions for using their product with other
materials.
The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

Main Processer
IC100 (DVF99) is main IC which controls almost IC's in this system.
And it has the acoustic echo canceller for 4 voice path.
IC503 (DCX81) is used for only echo canceller for another 4 voice path.
IC501 (DCX81) runs as DSP and RF circuit.

Power Supply Circuit
KX-NS0154 support 2 way power supply; AC adaptor and PoE (Power over Ethernet).
9V is supplied from AC adaptor through JK701.
48V is supplied from ethernet through JK302, and it is converted to 12V by IC303.
9V or 12V is converted 3.3V by IC702 (DCDC converter) and 1.8V by IC703 (DCDC converter).
IC701(Voltage regulator) regulates 1.2V from 1.8V.
9V is supplied from AC adaptor through JK701.

IC701(Voltage regulator) regulates 1.2V from 1.8V.
3.3V is used for Login and RF.
1.8V is used for DDR2 memory.
1.2V is used for core voltage of IC100, IC501 and IC503.
1.8V is used for DDR2 memory.
1.2V is used for core voltage of IC100, IC501 and IC503.
4.4.
Reset circuit
IC201 (Reset IC) detects supplied voltage from AC adaptor or PoE output, and it supplies Power-On-Reset signal to IC100
(DVF99).
IC100 supplies reset signal from GPIO to RSTN pin of IC501(DCX81 for RF) and IC503 (DCX81 for DSP).
Also IC100 supplies reset signal to IC302 (PHY).
