IC BLOCK DIAGRAM & DESCRIPTION
Power terminal for crystal oscillator
Joining terminal for crystal resonator (16.9344 MHz)
Ground terminal for crystal oscillator. Make sure to ground.
Output terminal for synchronizing signals of sub-code clock.
Monitor terminal for 1 bit or 2 bit error correction
Output terminal for sub-code P, Q, R, S, T, U or W.
Output terminal for synchronizing signals of sub-code frame. When sub-code is stood by, falls.
Input terminal for clock to read out sub-code. Schmitt input (when not used, make sure to ground.)
Output terminal for synchronizing signal (7.35 kHz) which is divided from crystal oscillator.
Output terminal for Q output standby of sub-code.
Input terminal for read/write control. Schmitt input.
Output terminal for Q output of sub-code.
Input terminal for command from micro-computer.
Input terminal either for clock to take in command input or for clock to take out sub-code from SQOUT.
Input terminal for reseting this LSI. Switches to "L" position for a moment at power-on.
Output terminal for test. Make sure to open circuit. (Normally "L" output)
Output terminal of 16.9344 MHz
Output terminal of 4.2336 MHz
Input terminal for test. Pull-down resistor incorporated. Make sure to ground.
Input terminal for chip selecting. Pull-down resistor incorporated. Make sure to ground when not controlled.
Input terminal for test. No pull-down resistor. Make sure to ground.
Note: Each power terminal (VDD, VVDD, LVDD, RVDD and XVDD) must be supplyed with the same voltage.
