PB C LPF is built in, so that a

signal with the AFM and ATF

components (Y RF + C RF)

eliminated can be input.

2.05V

RF SWP (switching pulse) and

HCHG (head change) pulse

input. Half H shift, HHS

cancel, ACC channel hold,

and PI/PS switching operate

at VTH = 0.7V. Yd playback

during playback operates at

VTH = 2.05V (same as when

mode Yd is High).

Input to BUS DECODER. CS

is used as chip select, and

data is latched at rising edge.

CK is the clock input. Use a

clock frequency fck of less

than 1.3MHz. SI is used as a

serial data input.
