PRELIMINARY DATA
Record Mode
The current input applied on RECIN Pin is amplified
through a transconductanceamplifier. Special care
has been taken to speed up commutation from
Playback to Record and from Record to Playback,
avoiding spikes through the loads (the rotary trans-
formers).

(Plastic Micropackage)
ORDER CODE : STV5727
DESCRIPTION
STV5727 is intended for 2 heads VCR applications.
It includes all the electrical functions necessary to
achieve play-back and record processing for VHS
applications.
Record or Playback Mode can be selected through
SWR Pin.
Playback Mode
Signals applied on H1 and H2 input pins will be
amplified by 60dB voltage gain. IOUTSP Pin is AC
short-circuited to ground by CCOM. The input sig-
nal can be selected through SWIN Pin and the
correspondingoutput signal will be available on Pin
CPB. The offset voltage between the two heads is
automatically cancelled after 32 switching head
cycles. A constant output signal will be available on
Pin YPB thanks to an AGC function (Automatic
Gain Control). The time constant of the AGC is
determined by the capacitor value connected to
CAGC Pin. For Automatic Tracking, a signal which
is a function of the selected input signal amplitude
is present on Pin TRIV. According to the voltage
level on SWIN Pin, the triv gain can be change.
