FSK Detection
Notes:
1: Both mark and space have the same amplitude and are at the nominal frequencies.
2: These characteristics are fort V
3: Band limited random noise 300 - 3400 Hz. Present only when the FSK signal is present.
AC Timing Characteristics
(AC timing characteristics supersede the recommended operating conditions unless otherwise stated.)
