0 dBm0, D
Note 12: Measured by grounded input at VF
Note 13: PPSR
Note 14: A signal is Valid if it is above V
Note 15: A multi-tone test technique is used.
Unless otherwise noted, limits printed in BOLD characters are guaranteed for V
gain), hybrid balance filter disabled. All other limits are assured by correlation with other production tests and/or product de-
sign and characterization. All signals referenced to GND. Typicals specified at V

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
