Errata information

13.1.1

FAST H-LOCK INDICATOR BIT

13.1.1.1

Issue

The H-lock indicator bit (HL_FAST, available on

RTS0/RTS1 and selectable with HLSEL via I2C-bus)

shows a static behaviour which doesn’t match the

specified function.

13.1.1.2

Impact

It is not possible to use the signal HL_FAST as fast

horizontal locking indicator bit for quick source switching.

This anomaly has minor impact for most video applications

since this feature will be used mainly for security

applications.

13.1.1.3

Work-around

Use of the normal flag HL or HLCK instead of HL_FAST.

13.1.2

FAST TIME CONSTANT HPLL

13.1.2.1

Issue

The damping factor of the digital horizontal PLL is too high.

13.1.2.2

Impact

It is not possible to use the new fast time constant with

VCR sources due to visible run-ins on the first lines.

13.1.2.3

Work-around

The old VCR time constant should be used.

13.1.3

FAST LOCKING MODE

13.1.3.1

Issue

The fast vertical locking mode VNL shows an undefined

behaviour which doesn’t match the specified function.

13.1.3.2

Impact

It is not possible to use the fast vertical locking mode VNL

since in some unknown circumstances the fast locking

mode needs more time for locking than the normal mode.

This anomaly has minor impact for most video applications

since this feature will be used mainly for security

applications.

13.1.3.3

Work-around

No recommendations for a functional replacement of this

feature.
