Power-Supply Bypassing
and Ground Management
The MAX9516 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 (VDD) with a 0.1F capacitor
to GND, placed as close to the device as possible.
Bypass VSS with a 1F capacitor to GND as close to
the device as possible. The total system bypass capac-
itance on VDD should be at least 10F or ten times the
capacitance between C1P and C1N.
Using a Digital Supply
The MAX9516 was designed to operate from noisy digi-
tal supplies. The high PSRR (54dB at 100kHz) allows
the MAX9516 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 resistance (ESR) and equivalent
series inductance (ESL).
