ACE9040J/IW/FP2N

Overview

The ACE9040 is a VHF oscillator, up-converter, and prescaler designed for offset modulated transmit architectures. It operates with a UHF synthesiser for channel selection and a second synthesiser generating a fixed transmit offset. The device accepts a VCO signal to drive an on-chip dual two-modulus prescaler and a transmit up-converter that suppresses the unwanted sideband. A buffered VHF oscillator drives an auxiliary synthesiser input and locks to the offset frequency, which is modulated by varying the external tank circuit resonant frequency. Both oscillators drive the up-converting mixer to generate the transmit signal. The component includes power saving modes allowing transmit section shutdown during stand-by and whole chip shutdown during sleep mode.

Feature Summary

• Integrated dual two-modulus prescaler driving main synthesiser inputs
• Single-sideband up-converter suppressing unwanted transmit sidebands
• VHF oscillator locked to offset frequency via external tank circuit modulation
• Configurable power saving modes for battery economy and sleep operation

Applications

• Offset modulated transmit architectures in radio systems
• UHF synthesiser channel selection interfaces
• Fixed transmit offset generation circuits

Procurement Notes

Verify the specific suffix codes against official Zarlink documentation to confirm package type and handling specifications. Ensure compatibility with the intended synthesiser architecture before procurement. Cross-reference ordering information to validate availability of the required variant.

Selection Notes

Select this component when designing offset modulated transmitters requiring integrated prescaling and up-conversion. Verify that the external VCO and tank circuit components meet the specified drive and resonance requirements. Confirm that the power saving features align with the system's standby and sleep cycle requirements.
