General Description

on page 8

Number of allowed BIC errors This IC’s synchronization circuit operates by recognizing a 16-bit BIC code.

The number of allowed errors is the number of allowed error bits in the 16 bits used for BIC recognition.

Key Features

  • rd and backward protection counts are set to 3. This IC defines the protection counter value to be 1 at the point where a match or a mismatch occurs between the IC internal ti.

Ordering number : EN5744 CMOS IC LC72705E FM Multiplex Receiver IC for VICS Systems Overview The LC72705E is a data demodulation IC for receiving FM multiplex broadcasts for mobile receivers in the DARC format. This IC includes a decoder circuit that performs the required VICS processing, and, in conjunction with a bandpass filter IC (either the LV3400M or the LV3403M), can form a compact yet high-functionality VICS reception system. Note that a contract with VICS Center is required to evaluate this IC and to produce end products that support VICS.
