DECT Transmitter

PMB 2220

General Description

The PMB 2220 is a high speed analog bipolar IC and is one

of the Siemens chipset for the Digital European Cordless

Telephone. Combined with PLL (i.e. PMB 2306) and a power

amplifier, the PMB 2220 device performs a complete DECT

transmitter. Additionally the phase locked loop can be

switched to receive mode and be used as a local oscillator for

the receiver mixer of PMB 2420.

Type

PMB 2220-S

Features

Package

P-SSOP-24-1 (Shrink, SMD)

• Either single VCO operation (for receive and transmit) or

dual VCO operation (one for receive and one for transmit)

possible

• 64/65-prescaler on chip

• Frequency doubler for receive and transmit mode with

balanced driver outputs

• Supply voltage regulator (with external pnp-transistor)

for the two VCO’s

• Power-down for the inactive VCO

• Current reference output for PLL charge pump to get

constant lock-in time

• Wide power supple range 3.0 … 5.5 V
