LC89170M
CD Player Text Data IC
Preliminary
Overview
The LC89170M is an IC that decodes the text data, such
as song names, stored in subcode channels R to W of a
compact disk’s read-in area.
Features
• Accepts the channel R to W subcode data through a
subcode interface.
• Can continuously output the channel R to W data for
each 1PACK24 symbol.
• Performs error detection (cyclic redundancy code) and
outputs both the data and the result of that check.
• Provides synchronization protection for the subcode
interface.
• Supports low-voltage operation (3.3 V)
• Provided in the miniature MFP-14S package.

LC89170M
Functional Description
• Subcode interface
The LC89170M accepts subcode data from the DSP using the EXCK, SBSO, SCOR, and WFCK pins. Figure 1 shows
the timing.
Figure 1 Subcode Interface Timing
SW1 sets the input or output state for the EXCK pin. This pin is provided for cases where a subcode interface shift clock
source, such as a CD-G decoder circuit, is present in the vicinity of the LC89170M. Figure 2 shows usage examples.
Figure 2 SW1 Usage Examples
The SW2 is selected according to the subcode block period, TB, input to the SCOR pin.
