A

� IC402/IC405 (CXD2064Q) This IC is a comb filter in the applicable field. Being a single high-precision Y/C chip, the 3-line comb filter performs the Y/C separation of the sub channel video signals that have been output from IC1301. � IC404/IC407 (ML6428CL1) This IC is a 6.7 MHz low-pass filter. � IC804/IC810 (IX3473CE) This IC is a 6.7 MHz low-pass filter, incorporating a 6 dB amplifier, for the sub screen. � IC811 (IX3474CE) This IC is a 30 MHz low-pass filter, incorporating a 6 dB amplifier, for the main screen (for HDTV).

B

� IC1701 A3675CE) (F This IC is designed to control the 6-channel PWM switching regulator. With 5 step-up switching regulator lines incorporated, the IC converts +10V to +2.5V, +3.3V and +5.8V. Also with a step-down switching regulator line incorporated, the IC converts +10V to +6.0V, -5.0V, +12V and +35V. The lines are individually turned on and off.
