MAX9947

AISG Integrated Transceiver

General Description

The MAX9947 is an AISG-compliant, fully integrated

Beneﬁts and Features

● Receiver Wide Input Dynamic Range

transceiver.

• -15dBm to +5dBm in 50Ω

The MAX9947 receiver offers a typical dynamic range of

20dB and integrates a bandpass filter that operates in the

2.176MHz frequency with a narrow 200kHz bandwidth.

● Variable Transmitter Output Level from +7dBm to

+12dBm

● AISG-Compliant Output Emission Profile

● AutoDirection Output

The MAX9947 transmitter integrates a bandpass filter that

is compliant with the AISG spectrum emission profile. It

can modulate OOK signals up to 115.2kbps. The output

power can be varied with external resistors from +7dBm

to +12dBm to compensate for loss in the external circuitry

and cabling.

● No Need of Microcontrollers to Handle Bus

Arbitration in Tower-Mounted Equipment

● Supports All AISG Data Rates

• 9.6kbps

• 38.4kbps

• 115.2kbps

The MAX9947 also features a direction output to facilitate

the RS-485 bus arbitration in tower-mounted equipment.

● Bandpass Filter Compliant with AISG Protocol

The MAX9947 is available in a small, 3mm x 3mm 16-pin

TQFN and is rated for operation in the -40°C to +105°C

temperature range.

Centered Around 2.176MHz

● 3.0V to 5.5V Voltage Supply

● Independent Logic Supply

Applications

● Base Stations

● Small, 3mm x 3mm 16-Pin TQFN Package

● Tower Equipment
