4、Description 1）RF receive mode MD-01(MC-01) at VDD = 3.0V, Tc = 25 ° condition, the receiversensitivity is -88dBm at the rate of 250Kbps , 10kbps rate when-98dBm, the digital channel filter bandwidth between the 58~650KHz bandwidth limit should be crystal proportional to the frequency. 2）RF transmit mode MD-01's output power between-30dBm ~ +1 dBm, and spuriousradiation in the frequency of 25MHz ~ 1GHz ,is -36dBm, at 47 ~ 74,87.

SCLK,CSn four port is configured as a simple 4-wire synchronous parallel ports, which are also used as a buffer to read and writedata. All the parallel port data transfer begins with the first byte, includinga read/write signal, the pulse signal and a 6-byte address. During the address and data transmission, CSn pin (chip select,active low) must be kept low. If the transfer to take to CSn high, the transmission will be terminated.

c) Phase shift keying Phase shift keying is in transit to maintain a certain Period to transmit data. 5）Wireless Control a) Running order When the power is turned on, the system mustbe reset. In one of two ways must be executed: automatic restart or manual restart From time to time re-configuration is as follows: SCLK set to "1" while SI is set to "0" to avoid pin control modemay arise.

c) Wireless wake-up (WOR) functionality This optional wireless wake-up function can make the MD-01periodically wake up from a deep sleep. This function WOR has twocontrol modes choose to rely on PKTCTRL1.AUTOSYNCbits. When this bit is set to "0", the module will be wireless wake up in the Event0 point in time, and enters the RX State Event1point, which will ensure access to RX state at the exact time.
