Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Warning:Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. NOTE:This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is needed. • Consult the dealer or an experienced radio/TV technician for help. WARNING: Due to the mains switch being located on the rear panel, the apparatus must be located in an open area without anything obstructing access to the mains switch. FOR UK: The mains lead is terminated with a moulded three pin plug. Should the plug on the flexible cord not be of the type for your socket outlets do not use an adaptor but remove the plug from the cord and discard. Carefully prepare the end of the supply cord and fit a suitable plug. The fuse must be replaced with one of the same rating. IMPORTANT The wires in this mains lead are coloured in accordance with the following code: Blue:Neutral Brown:Live Yellow & Green:Earth As the colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The wire which is coloured Blue must be connected to the terminal which is marked by the letter N or coloured Black. The wire which is coloured Brown must be connected to the terminal which is marked with the letter L or coloured Red. FOR EUROPE: A mains lead compatible with national earthing standards and complying with the local safety requirement is supplied. WARNING TO REDUCE THE RISK OF FIRE OR ELECTRICAL SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE • A combined mains power input lead and country specific mains plug is provided. • Check before connecting to your local mains supply that the local supply voltage is the same as that marked on the rear panel. If it is not, check with your supplier before proceeding. CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. Explanation of Graphical Symbols The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of a sufficient magnitude to constitute a risk of electrical shock to persons. The exclamation mark within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. SAFETY INFORMATION PSW4+5000 Manual ISSUE2 7/12/02 3:36 PM Page D Please take heed of the following before using the KEF Models PSW4000 and PSW5000.

Page 1December 2001 TX4915 Low Power ASK Transmitter IC Advance Information HiMARK Technology, Inc. reserves the right to change the product described in this datasheet. All information con- tained in this datasheet is subject to change without prior notice. HiMARK Technology, Inc. assumes no responsibility for the use of any circuits shown in this datasheet. Description The TX4915 is a low power ASK transmitter IC intended for applications in the North American and European VHF/UHF bands. The integrated voltage-controlled oscillator (VCO), phase/frequency detector, prescaler, and reference oscillator require only the addition of an external crystal to provide a complete phase-locked loop (PLL). In addi- tion to the standard power-down mode, the chip also includes an automatic lock-detect feature that disables the transmitter output when the PLL is out-of-lock. Features ‹Output frequency range: 100 – 960MHz ‹Supply voltage range: 2.2 – 3.6V ‹Low current consumption with power down capability ‹On-chip VCO with integrated PLL (÷ 64/128) dual modulus prescaler ‹Out-of-lock inhibit circuit ‹SSOP-16 package (0.64mm pitch) Applications ‹Wireless mouse ‹Car alarm and home security systems ‹Remote control systems Block Diagram the wireless IC company 78 TXEN OSC OUT OSC IN 2 1 VREFPVSS2VCC2RESRES OSC VCO Prescaler ÷ 64/128 DO PFD and CP 3456 109 15 1614131211 VSSTXOUTVSS1VCC1MODIN AMP LD SW LD BIAS TX4915 the wireless IC company Page 2December 2001 Package and Pin Assignment SSOP-16 (0.64mm pitch) Symbol Dimensions in mmDimensions in inches min.nom.max.min.nom.max.

The reference oscillator uses a modified Colpitts configuration. 2OSCOUTThis pin is connected directly to the emitter of the reference oscillator transistor. 3TXEN Transmitter enable control (TXEN = low = power down mode; TXEN = high = nor- mal operation mode). 4VSSGround connection for the transmit output amplifier. 5TXOUT Transmitter output. This pin is an open collector and requires a pull-up inductor for bias/matching and a tapped capacitor for matching. 6VSS1Ground connection for the transmit driver amplifier. 7VCC1Nominal supply voltage for the transmit driver amplifier. 8MODIN ASK modulation input. An external resistor is used to bias the entire transmit ampli- fier chain through this pin. 9VCC2Nominal supply voltage for the VCO and PLL circuitry. 10VSS2Ground connection for the PLL circuitry. 11VREFPBias voltage reference pin. 12RES Differential open collector VCO outputs. 13RES 14DO Output of the charge pump. An R-C network from this pin to ground is used to establish the PLL bandwidth. 15LD Lock detector output. This pin is used to set the threshold of the lock detect circuitry which enables or disables the transmit amplifier. A shunt capacitor should be used to set an R-C time constant with the on-chip series 1kΩ resistor. The time constant should be set to approximately 15 times the reference period. 16SWPrescaler modulus control input (SW = high = ÷ 64; SW = low = ÷ 128).

In particular, it is intended for transmitter applications in 315/433MHz band remote keyless entry and 868/915MHz ISM-band systems. In addition, the TX4915 possesses a PLL-only mode which allows it to be simply used as a local oscillator source. The integrated voltage-controlled oscil- lator (VCO), phase/frequency detector, prescaler, and reference oscillator require only the addition of an external crystal to provide a complete phase-locked loop. In addition to the normal operation mode, the chip also includes an automatic lock-detect feature that disables the transmitter output when the PLL is out- of-lock. Reference crystal…
