10FID

Non

Synchronous

Input

REFERENCE SIGNAL INPUT

Signal levels are LVCMOS/LVTTL compatible.

The 10FID external reference signal is applied to this pin by the

application layer. 10FID defines the field in which the video and audio

clock phase relationship is defined according to SMPTE 318-M. It is also

used to define a 3:2 video cadence.

NOTE: If the input reference format does not include a 10 Field ID signal,

this pin should be held LOW. See Section 3.4.2 on page 41.

16

HSYNC

Non

Synchronous

Input

REFERENCE SIGNAL INPUT

Signal levels are LVCMOS/LVTTL compatible.

The HSYNC external reference signal is applied to this pin by the

application layer. When the GS4901B/GS4900B is operating in Genlock

mode, the device senses the polarity of the HSYNC input automatically,

and references to the leading edge.

This signal must adhere to one of the 36 defined video standards

supported by the device. In this mode of operation, the HSYNC input

provides a horizontal scanning reference signal.

The HSYNC signal may have analog timing, such as from a sync

separator, or may be digital such as from an SDI deserializer. Section 1.4

on page 20 describes the 36 video formats recognized by the

GS4901B/GS4900B.

17

VSYNC

Non

Synchronous

Input

REFERENCE SIGNAL INPUT

Signal levels are LVCMOS/LVTTL compatible.

The VSYNC external reference signal is applied to this pin by the

application layer. When the GS4901B/GS4900B is operating in Genlock

mode, the device senses the polarity of the VSYNC input automatically,

and references to the leading edge.

This signal must adhere to one of the 36 defined video standards

supported by the device. In this mode of operation, the VSYNC input

provides a vertical scanning reference signal.

The VSYNC signal may have analog timing, such as from a sync

separator, or may be digital such as from an SDI deserializer. Section 1.4

on page 20 describes the 36 video formats recognized by the

GS4901B/GS4900B.

IO_VDD

–

Power

Supply

Most positive power supply connection for the digital I/O signals.

Connect to either +1.8V DC or +3.3V DC.

NOTE: All five IO_VDD pins must be powered by the same voltage.
