2. Memory Map Timing Characteristics
The following characteristics are defined over the Recommended Operating Conditions unless otherwise noted. Typical
values are for Tc = 40°C, Vcc33 = 3.3 V and Vcc25 = 2.5 V.
Notes:
1. Max values are valid where competing TWS traffic is absent.
2. The outputs of affected channels are disabled for incidences of Tx Fault and squelched for Tx LOS and/or Rx LOS. Timing for output fault and
