WEN SHING DATA SHEET Receiver Module : RWS-A916 (916.5MHz ) *Frequency Range: 916.5 MHz *Modulate Mode: ASK *Circuit Shape: PLL *Date Rate: 3K~100 Kbps *Sensitivity: -112 dB *Channel Spacing: 200 KHz *Supply Voltage: 2.7~ 5.5 V * High Sensitivity Passive Design. *Simple To Apply with Low External Count. -Designed for Short-Range Wireless Control and Data Communications -Supports RF Data Transmission Rates Up to 200 kbps -2.4 V, Low Current Operation plus Sleep Mode -Stable, Easy to Use, Low External Parts Count The RWS-A916 MODULE receiver is ideal for short-range wireless control and data applications where robust operation, small size, low power consumption and low cost are required. The RWS-A916 MODULE All critical RF functions are contained in the MODULE, simplifying and speeding design-in. The RWS-A916 is sensitive and stable. A wide dynamic range log detector, in combination with digital RSSI and a compound data slicer, provide robust performance in the presence of on-channel interference or noise. FCC 15.249 and similar regulations. CAUTION: Electrostatic Sensitive Device. Observe precautions when handling. Notes: 1. OOK BER measured with no DS1 threshold (DS2 disabled), and data encoded for DC-balance with a run length limited to 4 bit periods. 2. ASK BER measured with a 25 mV DS1 threshold, DS2 threshold 6 dB below peak, and data encoded for DC-balance with a run length limited to 4 bit periods. 3. Sleep to receive recovery time is for the sleep period and signal level indicated, -40 to 60 C.Recovery time will increase at higher temperatures, for longer sleep intervals and lower signal levels. 9600BSP to change 100KBPS cut capacitance a.b.c Absolute Maximum Rating Rating Value Units Power Supply and All Input/Output Pins -0.3 to +12.0 V Non-Operating Case Temperature -20 to +85 C Soldering Temperature (10 seconds) 230 C Electrical Characteristics, 200 kbps On-Off Keyed, Low-Current RX Mode 1 Characteristic Sym Operating Frequency Notes Minimum fO Typical Maximum Units 914.20 MHz 913.80 Modulation Type Data Rate Receiver Performance (OOK @ 2.4 kbps) ASK Input Current, 3.6 Vdc Supply IR 0.9 Input Signal for 10 BER, 25 C 1 Rejection, 30 MHz RREJ Sleep to Receive Switch Time (100 ms tSR mA -98 dBm 55 dB 3 200 us sleep, -85 dBm signal) Sleep Mode Current IS Power Supply Voltage Range VCC Operating Ambient Temperature TA 5 uA 2.7 5 Vdc -40 +85 C Electrical Characteristics, 19.2 kbps On-Off Keyed, High-Sensitivity RX Mode Characteristic Sym Notes Minimum fO 913.80 Operating Frequency Modulation Type OOK Data Rate 2.4 Receiver Performance (OOK @ 2.4 kbps) Typical Maximum Units 914.20 MHz kbps IR 1.8 mA Input Current, 3 Vdc Supply Input Signal for 10 BER, 25 C 1 Rejection, 30 MHz RREJ Sleep to Receive Switch Time (100 ms tSR -98 dBm 55 dB 3 200 us sleep, -85 dBm signal) Sleep Mode Current IS Power Supply Voltage Range VCC Operating Ambient Temperature TA 5 uA 2.7 3.5 Vdc -40 +85 C Electrical Characteristics, 115.2 kbps Amplitude-Shift Keyed, High-Sensitivity RX Mode Characteristic Sym Operating Frequency Notes Minimum fO 913.80 Typical Modulation Type OOK Data Rate 2.4 Receiver Performance (OOK @ 2.4 kbps) IR Maximum Units 914.20 MHz kbps 1.8 mA +98 dBm Input Current, 3 Vdc Supply Input Signal for 10 BER, 25 C 1 Rejection, 30 MHz RREJ Sleep to Receive Switch Time (100 ms sleep, tSR 55 3 dB 200 us -85 dBm signal) Sleep Mode Current IS Power Supply Voltage Range VCC Operating Ambient Temperature TA 5 uA 2.7 3.5 Vdc -40 +85 C Receiver Set-Up, 3.0 Vdc, -40 to +85 Item Symbol OOK OOK ASK Units Notes Nominal NRZ Data Rate DRNOM 2.4 19.2 115.2 kbps see pages 1 &2 Minimum Signal Pulse SPMIN 416.67 52.08 8.68 us single bit 2 Maximum Signal Pulse SPMAX 1666.68 208.32 34.72 us 4 bits of same value AGCCAP Capacitor CAGC - - 2200 pF 10% ceramic PKDET Capacitor CPKD - - 0.001 uF 10% ceramic BBOUT Capacitor CBBO 0.1 0.015 0.0027 uF 10% ceramic LPFADJ Resistor RLPF 240 30 12 K 5% RREF Resistor RREF 100 100 100 K 1% THLD2 Resistor RTH2 - - 100 K 1%, for 6 dB below peak THLD1 Resistor RTH1 10 27 100 K 1%, typical values PRATE Resistor RPR 1100 330 160 K 5% PWIDTH Resistor RPW 270 to GND 270 to GND 1000 toVCC k 5% DC Bypass Capacitor CDCB 10 10 10 F tantalum RF Bypass Capacitor 1 CRFB1 27 27 27 pF 5% NPO Antenna Tuning Inductor LAT 10 10 10 nH 50 ohm antenna Shunt Tuning/ESD Inductor LESD 100 100 100 nH 50 ohm antenna Application Note: 3 4 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 9 16 15 14 13 12 11 10 9 5 4 4 47K 47K 18 17 16 15 14 13 12 11 10 TWS-A916 18 17 16 15 14 13 12 11 10 1M 4 3 2 1 VDD DOUT OSC1 OSC2 TE AD11 AD10 AD9 AD8 VCC 5 V HT-12D 3 5 6 7 8 1 2 3 4 發發發發 A0 A1 A2 A3 A4 A5 A6 A7 VSS HT-12E C 4 A0 VDD A1 VT A2 OSC1 A3 OSC2 A4 DIN A5 D11 A6 D10 A7 D9 VSS D8 1 2 3 4 5 6 7 8 9 D 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 5 3 2 RWS - A916 Size A Date: 2 1 示示示示圖 接接發發 ( 接接接 8 接接) 控控發控控 星星星, 星星 01, 2001 Sheet D 1 VCC 5V 2 3 控控發 1 控控發 2 控控發 3 C 控控發 4 3 5 1 2 4 B B A A Title <Title> Document Number <Doc> Rev <RevCode> 1 1 of 1
