FUNCTIONAL OVERVIEW:
CYRF6936 provides complete WirelessUSB antenna wireless MODEM. designed implement wireless device links operating worldwide 2.4-GHz frequency band. intended systems compliant with world-wide regulations covered ETSI 489-1 V1.41, ETSI 328-1 V1.3.1 (Europe), Part (USA Industry Canada) TELEC ARIB_T66_March, 2003 (Japan). contains 2.4-GHz 1-Mbps GFSK radio transceiver, packet data buffering, packet framer, DSSS baseband controller, Received Signal Strength Indication (RSSI), interface data transfer device configuration. radio supports discrete 1-MHz channels (regulations limit some these channels certain jurisdictions). baseband performs DSSS spreading/despreading, Start Packet (SOP), Packet (EOP) detection CRC16 generation checking. baseband also configured automatically transmit Acknowledge (ACK) handshake packets whenever valid packet received. When receive mode, with packet framing enabled, device always ready receive data transmitted supported rates enabling implementation mixed-rate systems which different devices different data rates. This also enables implementation dynamic data rate systems, which high data rates shorter distances and/or low-moderate interference environment, change lower data rates longer distances and/or high interference environments. addition, CYRF6936 Power Management Unit (PMU) which allows direct connection device battery voltage range 1.8V 3.6V. conditions battery voltage provide supply voltages required device, supply external devices. Data Transmission Modes supports four different data transmission modes: GFSK mode, data transmitted Mbps, without DSSS. mode, bits encoded each derived code symbol transmitted. mode, 2-bits encoded each derived code symbol transmitted.

Both 64-chip 32-chip Pseudo-Noise (PN) Codes supported. four data transmission modes apply data after SOP. particular length, data, CRC16 sent same mode. general, lower data rates reduce packet error rate given environment. Link Layer Modes CYRF6936 device supports following data packet framing features: Packets begin with 2-symbol Start Packet (SOP) marker.

When length field enabled, Packet (EOP) condition inferred after reception number bytes defined length field, plus bytes CRC16 (when enabled-see below). alternative using length field infer condition from configurable number successive non-correlations; this option available GFSK mode only recommended enable when using mode. CRC16 device configured append 16-bit CRC16 each packet. CRC16 uses polynomial with added programmability seed. enabled, receiver will verify calculated CRC16 payload data against received value CRC16 field. seed value CRC16 calculation configurable, CRC16 transmitted calculated using either loaded seed value zero seed; received data CRC16 will checked against both configured zero CRC16 seeds.

Packet Buffers data transmission reception utilizes 16-byte packet buffers-one transmission reception. transmit buffer allows complete packet 16-bytes payload data loaded burst transaction, then transmitted with further intervention. Similarly, receive buffer allows entire packet payload data bytes received with firmware intervention required until packet reception complete. CYRF6936 supports packets bytes, however, actual maximum packet length will depend accuracy clock each link data mode; interrupts provided allow transmit receive buffers FIFOs. When transmitting packet longer than bytes, load 16-bytes initially, further bytes transmit buffer transmission data creates space buffer. Similarly, when receiving packets longer than bytes, must fetch received data from FIFO periodically during packet reception prevent from overflowing. Auto Transaction Sequencer (ATS) CYRF6936 provides automated support transmission reception acknowledged data packets. When transmitting transaction mode, device automatically: starts crystal synthesizer enters transmit mode transmits packet transmit buffer transitions receive mode waits packet transitions transaction state when either packet received, timeout period expires Similarly, when receiving transaction mode, device automatically:

Similarly, when receiving packets transaction mode, firmware simply needs retrieve fully received packet response interrupt request indicating reception packet. Backward Compatibility CYRF6936 fully interoperable with main modes first generation devices. 62.5-kbps mode supported selecting 32-chip mode. Similarly, 15.675-kbps mode supported selecting 64-chip mode. this way, suitably configured CYRF6936 device transmit data and/or receive data from first generation device. Disabling SOP, length, CRC16 fields required backwards compatibility. Data Rates combining code lengths data transmission modes described above, CYRF6936 supports following data rates: 1000-kbps (GFSK) 250-kbps (32-chip 8DR) 125-kbps (64-chip 8DR) 62.5-kbps (32-chip DDR) 31.25-kbps (64-chip DDR) 15.625-kbps (64-chip SDR)

Function Bits STRIM least significant bits synthesizer offset value. This 12-bit complement signed number which used offset transmit frequency device ±1.5 MHz. positive value increases transmit frequency, negative value reduces transmit frequency. value increases transmit frequency 732.6 value decreases transmit frequency 732.6 value 0x0555 increases transmit frequency MHz; value 0xAAB decreases transmit frequency MHz. Typically, this register loaded with 0x55 during initialization. Typically this feature used avoid need change synthesizer frequency when switching between frequency offset from synthesizer frequency; therefore, transmitting with offset allows same synthesizer frequency used both transmit receive.

However, class codes known "multiplicative codes" used; there chip codes with good auto-correlation cross-correlation properties where least significant chips themselves have good autocorrelation cross-correlation properties when used 32-chip codes. this case same eight-byte value loaded into this file used both chip chip symbols. When reading this file, eight bytes must read; fewer than eight bytes read from file, contents file will have been rotated number bytes read. This applies writes, well. Recommended Codes:
