Transmitter Theory of Operation Transmitter Chain The transmitter chain consists of a SAW coupled-resonator oscillator followed by a modulated buffer amplifier. The SAW Introduction coupled resonator output filter suppresses transmitter harmonics Murata’s TX-series hybrid transmitters are specifically designed for to the antenna. short-range wireless data communication applications. These transmitters provide robust operation, very small size, low power Transmitter operation supports two modulation formats, on-off consumption and low implementation cost.

When OOK modulation is chosen, the transmitter The transmitters can be readily configured to support a wide output turns completely off between “1” data pulses. When ASK range of data rates and protocol requirements. TX-series modulation is chosen, a “1” pulse is represented by a higher transmitters feature excellent suppression of output harmonics and transmitted power level, and a “0” is represented by a lower virtually no other RF emissions, making them easy to certify to transmitted power level. OOK modulation provides compatibility short- range (unlicensed) radio regulations. with first-generation ASH technology, and provides for power conservation. ASK modulation must be used for high data rates Transmitter Block Diagram (data pulses less than 200 µs). ASK modulation also reduces the Figure 1 is the general block diagram of the transmitter.

(Note that the resistor driving TXMOD must also be low in the power-down mode to minimize power-down current.) CNTRL1 and CNTRL0 are CMOS compatible inputs. These inputs must be held at a logic level; they cannot be left unconnected.

Pin Name Description 1 GND1 GND1 is the RF ground pin. GND2 and GND3 should be connected to GND1 by short, low-inductance traces. VCC1 is the positive supply voltage pin for the transmitter output amplifier and the transmitter base-band circuitry. VCC1 is 2 VCC1 usually connected to the positive supply through a ferrite RF decoupling bead which is bypassed by an RF capacitor on the supply side. See the description of VCC2 (Pin 16) for additional information. 3 NC No connection. Printed circuit board pad may be grounded or floating. 4 NC No connection. Printed circuit board pad may be grounded or floating. 5 NC No connection. Printed circuit board pad may be grounded or floating. 6 NC No connection. Printed circuit board pad may be grounded or floating. 7 NC No connection. Printed circuit board pad may be grounded or floating. The transmitter RF output voltage is proportional to the input current to this pin. A series resistor is used to adjust the peak transmitter output voltage. 0 dBm of output power requires 250 µA of input current. In the ASK mode, minimum output power occurs when the modulation driver sinks about 10 µA of current from this pin. In the OOK mode, input signals less than 220 mV completely turn the transmitter oscillator off. Internally, this pin appears to be a diode in series with a small resistor. Peak transmitter output power P for a 3 Vdc supply voltage is approximately: O 8 TXMOD P = 16*(I )2, where P is in mW, and the peak modulation current I is in mA O TXM O TXM A ±5% resistor value is recommended. In the OOK mode, this pin is usually driven with a logic-level data input (unshaped data pulses). OOK modulation is practical for data pulses of 200 µs or longer. In the ASK mode, this pin accepts analog mod- ulation (shaped or unshaped data pulses). ASK modulation is practical for data pulses 8.7 µs or longer. This pin must be low in the power-down (sleep) mode. Please refer to the ASH Transceiver Designer’s Guide for additional information on modula- tion techniques. 9 NC No connection. Printed circuit board pad may be grounded or floating. 10 GND2 GND2 is an IC ground pin. It should be connected to GND1 by a short, low inductance trace. 11 NC No connection. Printed circuit board pad may be grounded or floating. 12 NC No connection. Printed circuit board pad may be grounded or floating. 13 NC No connection. Printed circuit board pad may be grounded or floating. 14 NC No connection. Printed circuit board pad may be grounded or floating. 15 NC No connection. Printed circuit board pad may be grounded or floating. VCC2 is the positive supply voltage pin for the transmitter oscillator. Pin 16 must be bypassed with an RF capacitor, and must 16 VCC2 also be bypassed with a 1 to 10 µF tantalum or electrolytic capacitor. Power supply voltage ripple should be limited to 10 mV peak-to-peak. See the ASH Transceiver Designer’s Guide for additional information. CNTRL1 and CNTRL0 select the transmit modes. CNTRL1 high and CNTRL0 low place the unit in the ASK transmit mode. CNTRL1 low and CNTRL0 high place the unit in the OOK transmit mode. CNTRL1 and CNTRL0 both low place the unit in the power-down (sleep) mode. CNTRL1 is a high-impedance input (CMOS compatible). An input voltage of 0 to 300 mV is 17 CNTRL1 interpreted as a logic low. An input voltage of Vcc - 300 mV or greater is interpreted as a logic high. An input voltage greater than Vcc + 200 mV should not be applied to this pin. A logic high requires a maximum source current of 40 µA. A logic low requires a maximum sink current of 25 µA (1 µA in sleep mode). This pin must be held at a logic level; it cannot be left uncon- nected. CNTRL0 is used with CNTRL1 to control the operating modes of the transmitter. See the description of CNTRL1 for more 18 CNTRL0 information. 19 GND3 GND3 is an IC ground pin. It should be connected to GND1 by a short, low inductance trace. RFIO is the transmitter RF output pin. This pin is connected directly to the SAW filter transducer. Antennas presenting an impedance in the range of 35 to 72 ohms resistive can be satisfactorily matched to this pin with a series matching coil and a 20 RFIO shunt matching/ESD protection coil. Other antenna impedances can be matched using two or three components. For some impedances, two inductors and a capacitor will be required. A DC path from RFIO to ground is required for ESD protection. ©2010-2015 by Murata Electronics N.A., Inc. www.murata.com TX5000 (R) 4/24/15 Page 5 of 6
