Pin Descriptions

PIN NUMBER

PIN NAME

PIN FUNCTION

1

Composite Sync

Out

Composite sync pulse output; sync pulses start on a falling edge and end on a rising edge

2

Composite Video

In

AC coupled composite video input; sync tip must be at the lowest potential (positive picture phase)

3

Vertical Sync Out

Vertical sync pulse output; the falling edge of vert sync is the start of the vertical period

4

GND

Supply ground

5

Burst/Back Porch

Output

Burst/back porch output; low during burst portion of composite video

An external resistor to ground sets all internal timing; a 681k 1% resistor will provide correct timing for

NTSC signals

7

Odd/Even Output

Odd/even field output; high during odd fields, low during even fields; transitions occur at start of vert sync

pulse

8

VDD 5V

Positive supply (5V)

NOTES:

2. Please refer to TB347 for details on reel specifications.

3. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte

tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil

Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-

020.

4. For Moisture Sensitivity Level (MSL), please see device information page for EL1881. For more information on MSL, please see Technical Brief
