digital clp modem with adpcm codec s5t8 610 11 preliminary functional description the main feature of s5t8610 is the digital communication between the hand set and the base set. the device accepts analog voice signal through the txi pin. the analog signal is converted into digital signal by the internal voice codec. the digital voice signal is then compressed by adpcm into either 24kbps or 16kbps. the compressed signal is then digitally modulated by 8 dpsk algorithm. the modulated signal is converted into analog signal by internal modem dac and finally output to the fm transmitter, through the txo pin. txi modem dac fs = 48 khz 8 phase dpsk modulator adpcm encoder voice adc fs = 8khz txo at the receiving side, s5t8610 accepts the modem signal from the fm receiver, through the rxi pin, and converts it into digital by internal modem adc. the received signal is demodulated and decompressed into digital voice signal. the digital voice signal is finally converted into analog by the internal voice codec, output, through the rxo pin, to the external amplifier, and then to the speaker. rxi voice dac fs = 8 khz adpcm decoder 8 phase dpsk demodulator modem adc fs = 48khz rxo initially s5t8610 is in the idle state after being reset by either the power-on-reset or external hardware reset. as default, the s5t8610 is set to base set. for the base set, s5t8610 waits for the four bytes of the encryption id. for the hand set, s5t8610 must first receive the modem control command specifying the system is a hand set. after receiving the modem control command, s5t8610 must receive four consecutive bytes of encryption id for encryption. s5t8610 can accept the first command from the host 72 m sec after a reset. after the first command, the time between two consecutive commands must be at least 20 m sec.

digital clp modem with adpcm codec s5t8 610 13 preliminary encryption/decryption s5t8610 provides security by encryption. the encryption is achieved by using the scrambler within the modem. before starting an operation, the host must send encryption id to the s5t8610 . the encryption id uniquely initializes the scrambler. the encryption id can be any number with 20 bit length which makes decoding by others almost impossible (one in million). although the test and the loop back test modes require the encryption id, the id is not used for those functions. s5t8610 only accepts data with length of 8 bits. the three msb specify the command type. for encryption id, the three bits are 001. therefore, the 20 bits are divided into four 8 bit words and sent in sequence from the host. msb lsb bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0 0 0 1 first 5 bits of the encryption id bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0 0 0 1 second 5 bits of the encryption id bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0 0 0 1 third 5 bits of the encryption id bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0 0 0 1 last 5 bits of the encryption id adpcm s5t8610 compresses voice signals by adpcm with data rate of 24kbps or 16kbps. the default adpcm rate is 24kbps. the 24kbps adpcm has better sound quality than 16kbps adpcm. however, s5t8610 does not provide error detection and concealment for 24kbps because of the high data rate. when the received signal strength indicator (rssi) of rf module goes to high, the host can switch the adpcm data rate to 16kbps by sending the adcpm control command. s5t8610 offers error detection and error concealment for 16kbps adpcm. this function provides longer communication range with security guaranteed. by setting the ber_mute bit to 1, the modem is automatically set mute when the bit error rate is too high. when the rssi produces low signal or the ber pin shows indicates low bit error rate, the host can switch back the adpcm data rate to 24kbps to offer better sound quality.

digital clp modem with adpcm codec s5t8 610 15 preliminary synch/ber/jam pin the synch/ber/jam pin is used for three purposes. the first is to signal the host that the initial synchronization between the hand set and base set is established. the second, used only with 24kbps adpcm, is to signal the host that jamming is detected, with the pin finally showing the bit error rate (ber). the third function is used only with 16kbps adpcm operation mode. adpcm first pulse rest of pulses 24kbps initial synchronization jamming detection 16kbps initial synchronization bit error rate after receiving the encryption id from the host, the hand set and the base set modems exchange protocols to establish initial synchronization between them. immediately after the initial synchronization, the synch/ber/jam pin produces high for 10msec. the pin normally produces low. therefore, the first output of the synch/ber/jam pin is always the high signal for 10msec, representing the initial synchronization. while the 16kbps adpcm is running, s5t8610 can detect error and indicate the ber through the synch/ber/jam pin. when an error is detected, the pin is set high for a given time duration. the duration of the high signal represents the ber range. after producing high, the pin produces low for 20msec before detecting the next ber. the following table shows ber ranges with their assigned pulse duration. for ber lower than 1.99 10-8, the pin does not produce high since the error is insignificant. ber symbol error rate time between error pulse duration from to from to from to above 4.16 10-2 above 2-3 below 1 msec 20 msec 4.16 10-2 2.08 10-2 2-3 2-4 1 msec 2 msec 40 msec 2.08 10-2 1.04 10-2 2-4 2-5 2 msec 4 msec 60 msec 1.04 10-2 5.21 10-3 2-5 2-6 4 msec 8 msec 80 msec 5.21 10-3 2.60 10-3 2-6 2-7 8 msec 16 msec 100 msec 2.60 10-3 1.30 10-3 2-7 2-8 16 msec 32 msec 120 msec 1.30 10-3 6.51 10-4 2-8 2-9 32 msec 64 msec 140 msec 6.51 10-4 3.26 10-4 2-9 2-10 64 msec 128 msec 160 msec 3.26 10-4 1.63 10-4 2-10 2-11 128 msec 256 msec 180 msec 1.63 10-4 8.14 10-5 2-11 2-12 256 msec 512 msec 200 msec 8.14 10-5 4.07 10-5 2-12 2-13 512 msec 1.024 sec 220 msec 4.07 10-5 2.03 10-5 2-13 2-14 1.024 sec 2.048 sec 240 msec 2.03 10-5 1.02 10-5 2-14 2-15 2.048 sec 4.096 sec 260 msec 1.02 10-5 5.09 10-6 2-15 2-16 4.096 sec 8.192 sec 280 msec 5.09 10-6 2.54 10-6 2-16 2-17 8.192 sec 16.384 sec 300 msec 2.54 10-6 1.27 10-6 2-17 2-18 16.384 sec 32.768 sec 320 msec 1.27 10-6 6.36 10-7 2-18 2-19 32.768 sec 1 min 5.5 sec 340 msec
