DS90UB954-Q1: CSI_TX_SPEED

Hi Team,

If set to 1.6Gbps, the output frequency of 954mipi is fixed at 1.6Gbps
Or it can support up to 1.6Gbps, the maximum is 1.6Gbps.
Thanks ~

Hello Amelie,

using 1.6Gbps/lane means you can supply the 954 with any data rate below 1.6Gbps/lane but the 954 will output this data at a speed of 1.6Gbps/lane.

HI Hamzeh.

May I ask if the ISP connected 954 and ISP is only support 1.5Gbps, does it mean that 954 （output 1.6Gbps）can't work with such a ISP（1.5Gbps）?

Hello Amelie,

yes, this is correct!

In this case you need to use a lower CSI-speed at the 954 output. You can use either the 800Mbps/lane without changing the REFCLK, or you can use the 1472Mbps/lane if you change the REFCLK from 25MHz to 23MHz.
