Notes:
1. TCLKn is shown for TnCLKI = 0, where data is clocked in on falling edges for channel n. Data is clocked in on rising
2. The Negative Rail lead may be used to input an external loss of signal indication when control bit EXnLOS = 1. The

loss-of-signal indication must be present for a minimum of 8 TCLKn cycles. When control bit EXnLOS = 0, external
coding violations may be clocked in. When control bit EXnLOSP = 0, the external loss-of-signal. Code violations are
counted when TLOSn is high and the TCLKn edge occurs per the TnCLKI selection (see Note 1 above).
