ACE9020

Receiver and Transmitter Interface

DS4287

ISSUE 5.0

December 1997

ACE9020isaVHFoscillator, up-converterandprescaler.

It is used in an offset modulated transmit architecture where a

UHF synthesiser makes the channel selection and a second

synthesiser generates a fixed transmit offset.

A VCO signal drives a buffer in ACE9020 to feed an on-

chip prescaler and transmit up-converter. The prescaler is a

dual two-modulus divider and drives the main synthesiser

input of the ACE9030. The SSB up-converter suppresses the

unwanted transmit sideband.

Ordering Information

SSOP 28 lead package, code NP28

ACE9020B/KG/NP1S - anti-static sticks

ACE9020B/KG/NP1T - tape mounted

The VHF oscillator is buffered to drive the auxiliary

synthesiser input of the ACE9030 and is locked to the offset

frequency. This frequency is modulated by varying the

resonant frequency of the external tank circuit. Both this

oscillator and the UHF VCO drive the up-converting mixer to

generate the transmit signal.

Various power saving modes for battery economy are

included. These allow the transmit sections to be shut down

during stand-by and the whole chip can be shut down during

sleep mode. Thecircuit techniquesusedhave beenchosento

minimise external components and at the same time give very

high performance.
