General Description

The MAX7461 single-channel loss-of-sync alarm (LOS)

provides composite video sync detection in NTSC,

PAL, and SECAM standard-definition television (SDTV)

systems. The MAX7461’s advanced detection circuitry

delivers robust performance by preventing false loss-

of-sync alarms due to noise. The device accepts an

AC-coupled composite (CVBS), luma (Y), or any other

video signal with sync, and outputs a logic-level signal.

The open-drain LOS output is low when no sync is

detected and high impedance when sync is detected.

The device operates from a single +5V supply.

The MAX7461 is available in a 5-pin SOT23 package

and is specified for operation over the -40°C to +85°C

temperature range.
