NOTES
1
Sample tested at +25
°
C to ensure compliance. All input signals are specified with tr = tf = 5 ns (10% to 90% of 5 V) and timed from a voltage level of 1.6 V.
2
t
25
specifies a window, after Rx SYNC which marks the beginning of I data, that Rx SLEEP should be asserted for the subsequent IQ data pair to be last prior to
entering SLEEP mode.
3
See Figure 2 for test circuit.
4
Digital output rise and fall times specify the time required for the output to go between 10% and 90% of 5 V.
Specifications subject to change without notice.
