Functional Description

3.4.3 Stand-by / power down conditions

The PMB 2341 device has 2 different stand-by modes to reduce the power consumption.

The standby modes allow separate power up and down modes for the PLL itself and for

the RI input amplifier circuitry. The selection of a desired power-down mode is done by

setting two bits ‘standby1’ and ’standby2’ located in the A/N-counter control word (see

table 4-1: A/N counter data format).

This enables a fast wake-up of the device and programming of a VCO-frequency with

only one bus cycle!

The encoding of the defined modes can be obtained from table 4-5: standby mode

selection bits.
