Transmission Characteristics
Unless otherwise noted, limits printed in BOLD characters are guaranteed for V
+70˚C by correlation with 100% electrical testing at T
Transmit and receive gains programmed for maximum 0 dBm0 test levels (0 dB Gain). All other limits are assured by correla-
tion with other production tests and/or product design and characterization. All signals referenced to GND. Typicals specified at
V
Note 15: Measured by grounded input at V
Note 16: PPSR
Note 17: A signal is Valid if it is above V
Note 18: A multi-tone test technique is used.

a) All input signals are defined as: V
b) t
c) Delay Times are measured from the input signal Valid to the output signal Valid.
d) Setup Times are measured from the data input Valid to the clock input Invalid.
e) Hold Times are measured from the clock signal Valid to the data input Invalid.
f) Pulse widths are measured from V
