LC72707E - FM Multiplex Receiver

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

  • The protection count conditions are as follows.
  • Backward protection (unsynchronized, BLOCK = low) When the timing of the IC’s internal synchronization free-running counter matches that of.

Ordering number : EN5970 CMOS IC LC72707E FM Multiplex Receiver IC Supporting All Worldwide Standards Overview The LC72707E is a data demodulation IC for receiving FM multiplex broadcasts for mobile receivers in the DARC format. In conjunction with a bandpass filter IC (either the LV3400M or the LV3403M), the LC72707E can form a compact yet high-functionality FM multiplex reception system. This IC provides built-in DRIS system data processing decoder for Digital DJ CO.,LTD. Since supporting all the FM multiplex frame structures (methods A, A’, B, and C) in the ITU-R recommendations, this IC is optimal for use in radios for FM multiplex system. Note that a contract with Digital Incorporated is required to evaluate this IC and to produce end products that support DRIS. • 7.
