Preliminary specification
NTSC Picture-In-Picture (PIP) controller
SAB9082
Acquisition channel ADCs and clamping
The analog input signals are converted to digital signals by
three ADCs per channel. The resolution of the ADCs is
8 bits (DNL is 7 bits and INL is 6 bits) and the sampling is
performed at the system clock frequency of 28 MHz for the
Y input. A bias voltage (V
bias
) is used to decouple the AC
components on internal references.
The inputs should be AC coupled and an internal clamp
circuit (using external clamp capacitors) will clamp the
input to a level derived internally from V
ref(B)(MA/SA)
for the
luminance channels and, forthe chrominance channels, to
(V
ref(T)(MA/SA)
+ V
ref(B)(MA/SA)
)/2 + LSB/2. The clamping
starts at the active edge of the burst key. Internal video
buffers amplify the standard Y, U and V input signals to
the correct ADC levels.
PLL
The PLL generates an internal system clock of
1792
×
f
HSYNC
, from the f
HSYNC
, which is approximately
28 MHz.
DACs and video buffers
The 28 MHz digital video signals are fed to the 8-bit DACs
that produce the required analog video signals. The video
buffers amplify these signals prior to being fed to the
output to drive another device.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
QUALITY SPECIFICATION
In accordance with “SNW-FQ-611, Part E” dated 14 December 1992.
ESD LEVELS
The standard ESD specification is JEDEC Class II (2 kV Human Body Model, 200 V Machine Model) unless indicated
otherwise.
