reference oscillator controlled cheap ceramic resonator. types transmission mode available "Flash" "Carrier" mode. M709 simplified version M710 which only transmit commands with possible addresses. M710 other hand full system capacity transmit commands with addresses. M709 M710 produced with CMOS Si-gate technology available 28-pin dual in-line plastic packages respectively.
DIP24 (Plastic Package) ORDER CODE M709B1 M709AB1
DESCRIPTION These have been developed remote control consumer applications (TV, radio, video recorders) industrial field highly reliable transmission code which capacity 1024 channels. Each transmitted word structured into bits which constitute address bits which constitute command commands available). command 000000) used transmit "end transmission code when released. Additional bits transmitted synchronization transmitter receiver clocks security checks. address organization provides wide range simultaneous applications without interference between systems. receiver accepts decoded command only transmitted address matches address selected receiver. addresses available this purpose.

different code introduced even "1s" improves capability recognize false codes receiver end. example double error which cause exchange "10" with "01" easily detected. parity also added order further increase reliability transmission. This bits number transmitted "1s" even while number transmitted "1s" odd. addition, every word contains preliminary pulse, start pulse stop pulse. spacing between preliminary start pulse This followed after data pulses (one parity bit), terminated after interval stop pulse. Consequently, word which binary digit occurs times total duration 21T. word containing "1s" duration 36T.

SYNCHRONIZATION BETWEEN TRANSMITTER RECEIVER transmitter receiver operate with different reference frequencies. Typical values suitable correct operation system should between 510kHz, using cheap ceramic resonator. Synchronization between transmitter receiver, necessary obtain wide range frequency tolerance described above achieved measuring receiver interval between start pulse first data pulse, storing this value using time base KEYBOARD (pins CODE REPETITION column input connected input activate transmitter.
COMMAND TRANSMISSION CLOSED FLASH MODE CARRIER MODE
contact must continuously closed minimum 25ms. Double multiple contact operations accepted. command information repeatedly transmitted intervals 102ms (fref 500kHz) long push button remains operated. When contact interrupted circuit transmits, after pause about "end transmission code" returns stand-by mode. contact interrupted while command being transmitted circuit carries with transmission end. After pause about transmits transmission code. command accepted until "end transmission code" over.
