formats use CK as pixel clock; the other formats use CK2 as pixel clock. The first pixel is always aligned to the
leading edge of the HAV signal.
1.10.1. Validation Code Insertion
S5D0127X01 inserts validation codes during inactive video (HAV is inactive), and invalid video (HAV is active but
EHAV is inactive) to assist in recognition of scaled data and VBI data. Table 12 lists the available codes, when they
are inserted, and related programming registers.
An example timing diagram for some of the programmable modes is shown in Figure 35. In this diagram, The field
rate is 60 Hz, A CCIR 601 sampling rate has been selected thus giving 720 active pixels. The horizontal scaling
ratio has been selected for an output of 718 out of 720 pixels.

Description
INVALY
This user programmed code is inserted in the Y or G output stream in scaling operation when
HAV is active while EHAV is inactive. Insertion of this code is independent of the output
format. Related register is
INVALY
.
INVALU
This user programmed code is inserted in the U or B output stream in scaling operation when
HAV is active while EHAV is inactive. Insertion of this code is independent of the output
format. Related register is
INVALU
.
INVALV
This user programmed code is inserted in the V or R output stream in scaling operation when
HAV is active while EHAV is inactive. Insertion of this code is independent of the output
format. Related register is
INVALV
.
UNUSEY
This user programmed code is inserted in the Y or G output stream when HAV is inactive and
no other reference code is inserted. Insertion of this code is independent of the output format.
Related register is
UNUSEY
.
UNUSEU
This user programmed code is inserted in the U or B output stream when HAV is inactive and
no other reference code is inserted. Insertion of this code is independent of the output format.
Related register is
UNUSEU
.
UNUSEV
This user programmed code is inserted in the V or R output stream when HAV is inactive and
no other reference code is inserted. Insertion of this code is independent of the output format.
Related register is
