VIDIN7
Analog Video Inputs. The MAX4455 extracts video timing information from each VIDIN_
input. AC-couple the input signal with a 0.1μF capacitor.

V
H1
Host Interface Supply Voltage Input. V
H1
supplies the level shifters for logic outputs to the
host μP interface. Connect V
H1
to the μP logic supply.

OSDKEY7
OSDKEY Digital Outputs. OSDKEY_ logic low controls the fast mux switches (available in
the Maxim crosspoint switches, MAX4356/MAX4358) to insert OSDFILL_ signal.
65
V
K1
OSDKEY Interface Power-Supply Input. V
K1
supplies the level shifters for OSDKEY_ logic
outputs to the fast mux switches (available in the Maxim crosspoint switches,
MAX4356/MAX4358). Connect V
K1
to the digital supply of the fast mux switches (V
DD
of
the MAX4356/MAX4358).
73
XTAL1/SYNC
Crystal Oscillator/External Clock Input. Connect a crystal oscillator module to
XTAL1/SYNC, or connect a fundamental mode crystal oscillator between XTAL1/SYNC and
XTAL2.
74
XTAL2
Crystal Oscillator Output. Leave XTAL2 unconnected when using a crystal oscillator
module, or connect a fundamental mode crystal oscillator between XTAL1/SYNC and
XTAL2.

OSDFILL7
–
OSDFILL0
OSDFILL Analog Outputs. OSDFILL_ are video DAC current outputs and require a
termination resistor (nominally 75
) to AGND.
