The MAX9507 operates from a 1.7V to 2.625V single
supply and requires proper layout and bypassing. For
the best performance, place the components as close
to the device as possible.
Proper grounding improves performance and prevents
any switching noise from coupling into the video signal.
Bypass the analog supply (V
to GND, placed as close to the device as possible.
Bypass CPV

The MAX9507 is designed to operate from noisy digital
supplies. The high power-supply rejection ratio (47dB
at 100kHz) allows the MAX9507 to reject the noise from
the digital power supplies (see the Typical Operating
Characteristics ). If the digital power supply is very
noisy and stripes appear on the television screen,
increase the supply bypass capacitance. An additional,
smaller capacitor in parallel with the main bypass
capacitor can reduce digital supply noise because the
smaller capacitor has lower equivalent series resis-
tance (ESR) and equivalent series inductance (ESL).
