(1) This parameter was measured with an LMH1219EVM.
(2) This parameter was measured with an LMH1219EVM.
(3) IN1± can also be configured to lock to SMPTE data rates via register override control. For more information, refer to the LMH1219 Programming Guide.
(4) This parameter is data rate dependent. For example, at 11.88 Gbps, 1.5 UI = 1.5 x 84.17 ps = 126.25 ps. Therefore, TLatency = (126.25 + 220) ps = 346.25 ps.
