Camera InterfaceBasler A500k Series 2-21PRELIMINARYframe valid bit will become low at the same time as line valid indicating that a valid frame isno longer being transmitted.• Frame valid will remain low for at least 15 pixel clock cycles until the next frame starts.Figure 2-9 shows the data sequence when the camera is operating in edge-controlled or level-controlled exposure mode and Figure 2-10 shows the data sequence when the camera isoperating in programmable exposure mode.Figure 2-9: 8 Bit Output Mode with Edge or Level-controlled Exposure for the A501k/kcE x S y n cS ig n a lF ra m eVa lidL in eVa lid L in e 1 L in e 2 Lin e 10 24P ix e lC lo ck(5 0 M H z)m in . 3 μ s0 .1 μ s 0 .4 μ s 1 2 .8 μ s1 3 .2 μ s0 μ s1 3 .5 1 7 m sD _ 0P ix e l D a ta(8 b its)1 2 7 7 1 27 91 3 1 27 91 1 2 7 7 12 791D _ 1P ix e l D a ta(8 b its)1 2 7 8 1 28 02 4 1 28 02 1 2 7 8 12 80234..5..511 222 02 0 11 222 02 0This diagram assumes that the area of interest feature is not being used. With the area of interest feature enabled, thenumber of pixels transferred could be smaller.
