HORIZONTAL CLAMPING AND BLANKING
Rev. B | Page 21 of 36
The AD9949’s horizontal clamping and blanking pulses are fully
programmable to suit a variety of applications. Individual
sequences are defined for each signal, which are then organized
into multiple regions during image readout. This allows the
dark pixel clamping and blanking patterns to be changed at
each stage of the readout to accommodate different image
transfer timing and high speed line shifts.
INDIVIDUAL CLPOB AND PBLK SEQUENCES
The AFE horizontal timing consists of CLPOB and PBLK, as
shown in Figure 21. These two signals are independently
programmed using the parameters shown in Table 18. The start
polarity, first toggle position, and second toggle position are
fully programmable for each signal. The CLPOB and PBLK
signals are active low and should be programmed accordingly.
Up to four individual sequences can be created for each signal.
INDIVIDUAL HBLK SEQUENCES
The HBLK programmable timing shown in Figure 22 is similar
to CLPOB and PBLK. However, there is no start polarity
control.
Only the toggle positions are used to designate the
start and the stop positions of the blanking period. Additionally,
there is a polarity control, HBLKMASK, which designates the
polarity of the horizontal clock signals H1 to H4 during the
blanking period. Setting HBLKMASK high sets H1 = H3 = low
and H2 = H4 = high during the blanking,
as shown in Figure 23.
Up to four individual sequences are available for HBLK.
