The minimum/maximum specifications are guaranteed over this range.
Guaranteed by characterization.
Maximum LLC frequency is 110 MHz.
TTL input values are 0 V to 3 V, with rise/fall times of ≤3 ns, measured between the 10% and 90% points.
SDP timing figures obtained using default drive strength value (0xD5) in Register Subaddress 0xF4.
CP timing figures obtained using maximum drive strength value (0xFF) in Register Subaddress 0xF4.
DDR timing specifications dependent on LLC output pixel clock; TLCC/4 = 9.25 ns at LLC = 27 MHz.
