6.6 Timing Requirements
Turnon time, no signal at P_IN, Low-High transition EN, V_OUT to 90%
t_ON
Turnon time, no signal at P_IN, Low-High transition EN, V_OUT to 90%
T_A = –40°C to +85°C
Rise time⁽¹⁾, P_IN = no signal to 0 dBm, V_OUT from 10% to 90%
t_R
Rise time⁽¹⁾, P_IN = no signal to 0 dBm, V_OUT from 10% to 90%
T_A = –40°C to +85°C
Fall time⁽¹⁾, P_IN = no signal to 0 dBm, V_OUT from 90% to 10%
t_F
Fall time⁽¹⁾, P_IN = no signal to 0 dBm, V_OUT from 90% to 10%
T_A = –40°C to +85°C
(1) This parameter is ensured by design and/or characterization and is not tested in production.
