To meet DSC specifications, a 30ppm xtal, or better, is required.
Sub-Audio Detection Level threshold set to 16mVrms (CTCSS) or 44mVpk-pk
(DCS).
Tested as per TIA-603 C.
Inband Tone Detection Level threshold set to 16mV.
AVDD = 3.3V, for a â101010101 ⦠01â pattern measured at the input amplifier
feedback pin. Signal level scales with AVDD.
With sub-audio dropout time (P2.5) set to default. The typical dropout immunity is
approximately 40ms more than the programmed dropout time. The typical de-
response time is approximately 90ms longer than the programmed dropout time.
See section 9.2.3, P2.5 in the CMX7031/CMX7041 User Manual.
Immunity to signal drop-outs of up to the specified duration.
