2. Sync Detect Description
2.1 Changes to document:
In the Sync Detect description information on page 15 in the TFP401(A) datasheet and
page 14 in the TFP201(A), TFP101(A) datasheet change:
FROM
The TFPX01 offers an output, SCDT to indicate link activity. The TFPX01 monitors
activity on DE to determine if the link is active. When 1 million (1e6) pixel clock periods
pass without a transition on DE, the TFPX01 considers the link inactive and SCDT is
driven low. While SCDT is low, if two DE transitions are detected within 1600 pixel clock
periods, the link will be considered active and SCDT is pulled high.
TO
The TFPX01 offers an output, SCDT, to indicate link activity. The TFPX01 monitors
activity on DE to determine if the link is active. When 2^18 clocks produced by an on-chip
free running oscillator whose frequency is around 10-15 MHz pass without a transition on
DE, the TFPX01 considers the link inactive and SCDT is driven low. Hence SCDT goes
low after the terminal count of the counter is reached that is 17~26 ms. When SCDT is
low, if 8 DE edges are detected within the terminal count of 2^18 clocks, the link is
considered active and SCDT goes high.
In the Sync Detect description information on page 14 in the TFP403 datasheet change:
FROM
The TFP403 offers an output, SCDT to indicate link activity. The TFP403 monitors activity
on DE to determine if the link is active. When 1 million (1e6) pixel clock periods pass
without a transition on DE, theTFP403 considers the link inactive and SCDT is driven low.
The SCDT goes high immediately after the first transition on DE. The SCDT again
becomes low when no more transitions are seen after 2^18 oscillator clocks.
TO
The TFP403 offers an output, SCDT to indicate link activity. The TFP403 monitors activity
on DE to determine if the link is active. When 2^18 clocks produced by an on-chip free
running oscillator whose frequency is around 10-15 MHz pass without a transition on DE,
the TFP403 considers the link inactive and SCDT is driven low. Hence SCDT goes low
after the terminal count of the counter is reached that is 17~26 ms. When SCDT is low, if
8 DE edges are detected within the terminal count of 2^18 clocks, the link is considered
active and SCDT goes high.
