ESGEN vs. traditional Genlock

The example in

figure 67

, on page 84, uses ESGEN Genlock. Traditional genlock, such as is

output by an Extron BBG 6 A Blackburst Generator, can also be used in many applications.
See the attributes of the two timing references, below, to determine which to use in your
application.

ESGEN Genlock attibutes —

ESGEN Genlock uses the pixel clock, so it works for all resolutions and frame rate
combinations.

ESGEN Genlock is a proprietary signal, it can be used only with certain Electrosonic
products acquired by Extron.

The cable length is limited to 4 feet (1.2 m).

The recommended limit for daisy chaining ESGEN genlock is three units. Beyond
that, an Extron PDA 108 Player Sync Distribution Amplifier for JMP 9600
(part number 60-1148-01) should be used to maintain signal integrity.

Traditional Genlock attributes —

Traditional Genlock is expected to be NTSC (29.97 Hz) or PAL (25 Hz), so it is limited to
certain resolutions and frame rate combinations.

NOTE: The JMP 9600 can accept a standard NTSC standard definition bi-level

genlock signal and use it to lock a 1080i signal at 59.94 FPs or 1080p signal
at 29.97 FPS.

Traditional Genlock is very common, so it can be used with a wide variety of non-Extron
system components.

The cable length can be more than 100 feet (30 m).
