Remote Control Encoder IC

PT2607

FUNCTION DESCRIPTION

OPERATION

Transmission is enabled by setting any one of the data pins -- D12 to D15 to “HIGH” (for PT2607

version) or by setting the TE (for PT2607B and PT2607C versions).

For PT2607 version, when transmission enable signals from Pins -- D12 to D15 -- are received,

PT2607 begins a three-word transmission cycle. This three-word transmission cycle will continue as

long as the transmission enable (D12 to D15) is held “HIGH”. When D12 to D15 goes to “LOW” (that is,

the transmission enable become “LOW”), the encoder output completes its final three-word

transmission cycle and then stops. Please refer to the diagram below.
