DS90UB954-Q1: Regarding max resolution support for pattern generation

Sathyakam Medavaram

Part Number: DS90UB954-Q1

Dear TI,

I need below information for pattern generation use only (without cameras attached to deserializer)

Can DS90UB954 support pattern generation with 6192x6192 resolution for RGB565, RAW8, RAW10 & RAW12 formats?

We are not considering FPS and we just like to capture the images at CSI Rx for verification.

Thanks

    Hello,

    Yes if FPS is not a concern the 954 should be able to handle that resolution with those data types. Below is an example script from the datasheet for patgen:

    WriteI2C(0x33,0x01) # CSI0 enable
WriteI2C(0xB0,0x00) # Indirect Pattern Gen Registers
WriteI2C(0xB1,0x01) # PGEN_CTL
WriteI2C(0xB2,0x01)
WriteI2C(0xB1,0x02) # PGEN_CFG
WriteI2C(0xB2,0x33)
WriteI2C(0xB1,0x03) # PGEN_CSI_DI
WriteI2C(0xB2,0x24)
WriteI2C(0xB1,0x04) # PGEN_LINE_SIZE1
WriteI2C(0xB2,0x0F)
WriteI2C(0xB1,0x05) # PGEN_LINE_SIZE0
WriteI2C(0xB2,0x00)
WriteI2C(0xB1,0x06) # PGEN_BAR_SIZE1
WriteI2C(0xB2,0x01)
WriteI2C(0xB1,0x07) # PGEN_BAR_SIZE0
WriteI2C(0xB2,0xE0)
WriteI2C(0xB1,0x08) # PGEN_ACT_LPF1
WriteI2C(0xB2,0x02)
WriteI2C(0xB1,0x09) # PGEN_ACT_LPF0
WriteI2C(0xB2,0xD0)
WriteI2C(0xB1,0x0A) # PGEN_TOT_LPF1
WriteI2C(0xB2,0x04)
WriteI2C(0xB1,0x0B) # PGEN_TOT_LPF0
WriteI2C(0xB2,0x1A)
WriteI2C(0xB1,0x0C) # PGEN_LINE_PD1
WriteI2C(0xB2,0x0C)
WriteI2C(0xB1,0x0D) # PGEN_LINE_PD0
WriteI2C(0xB2,0x67)
WriteI2C(0xB1,0x0E) # PGEN_VBP
WriteI2C(0xB2,0x21)
WriteI2C(0xB1,0x0F) # PGEN_VFP
WriteI2C(0xB2,0x0A)

    Just be sure to update the registers for line size and active lines per frame.  Also total lines and verticle front porch and back porch will need to be updated to work with your system.  Also be sure to update indirect register 0x03 for the datatype.  

    If the frame rate doesn't matter then the 954 should be able to generate an image that large.  I suggest setting the patgen line period registers to a very high value so to keep the FPS low.

    Regards,

    Nick
