Transmitter Electrical 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:

* For control signal timing including Adr[2:0], IntL, ResetL, SCL and SDA see Control Characteristics: Transmitter/Receiver.

1. Supply current includes that of all Vcc25 contacts.

2. Supply current includes that of all Vcc33 contacts.

3. Measured over the range 100 MHz to 3.75 GHz with reference differential impedance of 100

Ω

4. Measured over the range 100 MHz to 3.75 GHz with reference common mode impedance of 25

Ω

5. Measured over the range 100 MHz to 3.75 GHz with reference differential impedance of 100

Ω

6. LOS Hysteresis is defined as 20 Log(LOS De-assert Level / LOS Assert Level).

7. Power On InitializationTime is the time from when the supply voltages reach and remain above the minimum Recommended Operating Conditions

to the time when the module enables TWS access. The module at that point is fully functional.
