Compact Handsfree Unit PHF­3 NHE­8/9

Introduction
General
The PHF­3 is a handsfree unit for handportable (NHE­6 and NHK­6) phones. It provides rapid charging for the phone and a possibility to use HF­operation. The PHF­3 cannot be connected directly to the phone but via the external antenna unit AAH­1D and mobile holder MBT­5 or other devices that provide the HF connector.

Technical Summary
Operation
The PHF­3 has external connections to car battery, ignition sense, car radio muting, external microphone and external speaker. The unit has a HF­connector that provides an interface to the phone via external antenna unit. The connection can be made directly or using the extension cable between PHF­3 and AAH­1D. There is also an internal speaker inside the handsfree unit. The unit consists of a switching mode rapid charger, HF­speaker and HF­microphone amplifiers, volume control circuit, voltage regulators, control circuit (microprocessor) and a CAP compatible interface. The PHF­3 is always connected to the car battery. To save the car battery, PHF­3 goes in to the sleep mode if the car is not running and/or the phone is not connected.

Modes of Operation
Phone not connected (sleep mode): When the phone is not connected the current consumption of the device has been minimized. The switching mode power supply (SMPS) and audio circuits has been turned off. PHF­3 is only waiting a phone to be connected. Phone connected (active mode): When the phone is connected to the PHF­3 it goes into the active mode. In the active mode the device provides charging current to the phone via SMPS. It also can provide hands free call option using the internal or the external speaker (if connected) and the external microphone. If more private call wants to be made, the phone itself can be used as a handset without losing the external antenna connection. The phone controls all the basic functions of PHF­3 that are required for making calls. In the active mode the PHF­3 follows the commands received from the phone via mbus. PHF­3 also provides car radio mute function during call. This is possible only in those radios which support that function. PHF­3 can control the mobile antenna motor if it is installed to the car.

This block converts signal levels and also provides single­ended to differential and level conversions as well as hook pulldown and device identification. Power Supply The circuits provides regulated operation voltages to every block. It regulates +3V3 for the operating voltage of MCU, +10V for operating voltage to audio amplifiers, +5V for bias voltage to audio amplifiers and for the microphone. +2V is for bias voltage to audio attenuation switches. The power supply voltages has been designed to achieve maximum ripple voltage rejection. Microphone Amplifier This block is a high performance handsfree microphone amplifier. The microphone and microphone amplifier are biased from the +5V. +10V is used as operating voltage for the amplifier. The amplifier gain is 30 dB nominal and input impedance is 2 kW. The output AC voltage is about 100 mV. The output impedance is as low as possible. The circuit performs the sum operation with minimum phase shift. The amplifier can be muted with the MCU. When microphone is not connected, the input of the microphone amplifier is grounded. Xear Amplifier The circuit performs differential to single­ended conversion of incoming audio signal. The circuit gain is 0 dB. Output DC bias in XEAR line is 1.8 V, input is AC coupled and the stage tolerates about ± 1.5 V combined common mode and differential mode input swing without clipping. Volume Control and Mute The circuit is the audio attenuator. Attenuation is performed with operational amplifiers and audio switches. The circuit performs 8 different audio levels (one is mute). Attenuation is adjustable with 4 dB steps from 0 dB to 28 dB and mute. MCU controls attenuation switches with 4 IO­lines, where one of them is the mute. Speaker Amplifiers The Preamplifier The preamplifier is an AC coupled single ended input stage for the power amplifier. The preamplifier makes most of the XEAR signal amplifying. It uses the +10 V operating voltage and it is biased to +5 V. Preamplifier has a fixed gain.

The Power amplifier (PA) The power amplifier is am AC coupled full bridge output stage with fixed gain. It's output impedance is 8 W and it is also biased to +5 V. Operating voltage is + 10 V. The both speaker outputs SP+ and SP­ are connected to the internal speaker connector via the external speaker connector. When the external speaker is connected, the internal speaker is then muted. Total gain for both pre­ and power amplifier is about 28 dB. Maximum output power with the internal speaker is 1.6 W and 3.1 W with the external speaker. Charger Charger is the switching mode power supply type. The nominal output voltage of charger is 10.2 V without load. Limits of the output voltage with all tolerances are 9.3 V to 10.8 V. Nominal output current is 780 mA and limits with tolerance are 714 mA to 832 mA. MCU controls functioning of the charger and checks the output voltage. Charger is short circuit protected. Control Circuit (MCU) Micro controller unit (MCU) controls all the functions of the PHF­3. It communicates with the phone by using the MBUS­line. It has an 8­bit AD­converter and several IO­lines to control functioning of the other blocks. External I/O and AD­converters This block is used to measure specified voltages. It also controls the mobile antenna motor (AMC) and the car radio mute (CMR). Specified voltages are car battery voltage +VB, ignition sense voltage (IGNS) and phone charging voltage +VC. For CRM and AMC current are also controlled by this block. Connectors There are 4 external connectors to other units, and one internal speaker connector. These external connectors are the car connector, the system connector, the microphone connector and the speaker connector. Input Protection The purpose of the input protection is to prevent ESD, RF and high or negative input voltages to damage the module. Contacts that are subject to ESD are protected with diode pairs. All inputs are protected from RF.
