ACE9020 is a VHF oscillator, up-converter and prescaler.
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.
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. The circuit techniques used have been chosen to
minimise external components and at the same time give very
high performance.
