Sync Separator 50% Slice S-H Filter HOUT
Description of Operation
Contd
The vertical circuit senses the CS edges and ini-
tiates an integrator which is reset by the shorter
horizontal sync pulses but times out the longer
vertical sync pulse widths The internal timing
circuits are referenced to IOT and VR3 the tim-
out period being inversely proportional to the
timing current The vertical output pulse is start-
ed on the first serration pulse in the vertical in-
terval and is then self-timed out In the absence
of a serration pulse an internal timer will default
the start of vertical
The Horizontal circuit senses the CS edges and
produces the true horizontal pulses of nominal
width 5
ms The leading edge is triggered from
the leading edge of the input H sync with the
same prop delay as the composite sync The half
line pulses present in the input signal during ver-
tical blanking are eliminated with an internal 2 H
eliminator circuit The 2 H eliminator circuit ini-
tiates a time out period after a horizontal pulse if
generated The time out period is a function of
IOT which is set by RSET
The back porch is triggered from the sync tip
trailing edge and initiates a one-shot pulse The
period of this pulse is again a function of IOT and
will therefore track the scan rate set by RESET
The oddeven circuit circuit (OE) is comprised
of flip flops which track the relationship of the
horizontal pulses to the leading edge of the verti-
cal output and will switch on every field at the
start of vertical Pin 13 is high during the odd
field
Loss of video signal can be detected by monitor-
ing the No Signal Detect Output pin 10 The
VTIP voltage held by the sample and hold is
compared with a voltage level set by RLV on pin
2 Pin 10 output goes high when the VTIP falls
below RLV set value
VTIP voltage is also passed through an amplifier
with gain of 2 and buffed to pin 9 This is done to
provide an indication of signal strength
The
Level Output signal can be used for AGC applica-
tions
