... REMOTE CONTROL DECODER PAIRED WITH SC5262 DESCRIPTION The SC5272 is a remote control decoder paired with SC5262 utilizing CMOS technology. It has a maximum of 12-bits of tri-state address pins 12 providing up to 531,441( address codes; thereby, drastically reducing any code collision possibilities. FEATURES * Low power consumption and very high noise immunity ...

... NC FUNCTION DESCRIPTION The SC5272 decodes the waveform received and fed into the Din pin. The waveform is decoded into code word that contains the address, data and Sync bits. The decoded address bits are compared with the address set at the address input pins. If both addresses match for 2 consecutive code words, SC5272 drives: a). The data output pins whose corresponding data bits is then decoded " ...

... OSC1 and OSC2 pins. For SC5272 to decode correctly the received waveform, the oscillator frequency of SC5272 must be 2.5 ~8 times that of transmitting SC5262 good practice to center the SC5272 oscillator frequency in the window to gain best window margin at both sides. The typical oscillator frequency with various resistor values for both SC5262 and SC5272 are shown below: HANGZHOU SILAN MICROELECTRONICS CO ...

... For a transmission to be valid, (1) it must be a complete code word, and (2) the address bits must match the address setting at the address pins. After two consecutive valid transmission, SC5272 (1) drives the data pins according to the data bits received, and (2) rise VT to high voltage(high state). ...

... LATCH or MOMENTARY DATA OUTPUT TYPE The SC5272 uses either the latch or momentary data output type depending on the SC5272 version used. The latch type SC5272-LXactivates the data out during transmission and this data is sustained in the memory until another data is inputted or entered. A momentary type(SC5272-MXon the other hand, activates the data out only during transmission ...

... Decoder With Data Output Pins 1. When the power is turned on , the SC5272 activates the Stand-By Mode then searches for signal. If there is no signal received, it remains in the Stand-By Mode; otherwise, the address bits are compared with the address configuration of the pins. 3. Whenever the address bits in frame match with that of the address configuration of the pin, the data bits are stored into memory ...
