NOTES:
1. There are no ESD protection diodes between pins 42, 43 and V_CC to allow higher AC peak voltage. The ESD protection level has thus been
reduced. Proper ESD handling precautions should be followed.

1. Sleep mode (PLL OFF, Rx OFF, Tx OFF)
In this mode everything is switched off except the 3–wire digital bus.
As long as the digital supply is still on, the programmed values are
active and the 3–wire bus will continue to be programmable.
2. Wait Mode (Tx Off, Rx Standby)
PLL is on. Receiver is in the reduced current standby mode and the
transmitter is completely switched off. This mode maybe useful if the
PLL is to be kept on and is waiting for a quick turn–on to either
transmit or receive modes, especially when Rx outputs are AC
coupled.
3. Transmit mode (Rx standby)
The PLL and transmitter are on. The receive section is in a reduced
current mode wherein most of the Rx circuitry is powered down
except for the bias and baseband circuits needed to hold the
baseband output voltages in the active state. This mode is useful if
the Rx baseband outputs are AC coupled via a large capacitor and
the application demands quick turn–on for the Rx, from Tx.
4. Receive Mode (Tx Off)
The Transmitter is completely shut–off. The PLL and receiver
sections are operating.
5. Transmit Mode (Rx OFF)
PLL and Transmit sections are on. However, the Receiver is
completely shut–down. This mode is useful if the Rx baseband
outputs are DC coupled to the external world.
