Power-Supply Bypassing and Ground
Management
The MAX9509/MAX9510 operate from a 1.7V to 2.625V
single supply and require 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 MAX9509/MAX9510 were designed to operate
from noisy digital supplies. The high PSRR (49dB at
100kHz) allows the MAX9509/MAX9510 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 induc-
tance (ESL).
