ACE9040J/IW/FP1Q

Overview

The ACE9040J/IW/FP1Q is a VHF oscillator, up-converter, and prescaler manufactured by Zarlink Semiconductor. It operates within an offset modulated transmit architecture where a UHF synthesizer handles channel selection and a secondary synthesizer generates a fixed transmit offset. The device accepts a VCO signal to drive an on-chip dual two-modulus prescaler and a single-sideband (SSB) up-converter that suppresses unwanted sidebands. A buffered VHF oscillator drives the auxiliary synthesizer input and locks to the offset frequency, which is modulated via an external tank circuit. The component supports various power-saving modes for battery economy.

Feature Summary

• Integrates a VHF oscillator, SSB up-converter, and dual modulus prescaler
• Suppresses unwanted transmit sidebands in offset modulation architectures
• Supports multiple power saving modes including standby and sleep shutdown

Applications

• Offset modulated transmit architectures
• UHF synthesizer systems with fixed transmit offsets
• Battery-powered communication equipment requiring power management

Procurement Notes

Verify the specific suffix IW/FP1Q against official datasheets to confirm package type and temperature range. Ensure compatibility with the intended VCO input levels and external tank circuit requirements. Confirm pinout alignment with the target PCB layout before procurement.

Selection Notes

Select this component when designing systems requiring integrated VHF oscillation and up-conversion. Verify that the external UHF synthesizer matches the required channel spacing. Ensure the design accommodates the necessary external tank circuit components for frequency modulation stability.

Part Context

This part belongs to the ACE90xx series of RF interface components from Zarlink. It complements devices like the ACE9030 by providing the front-end oscillation and conversion stages. The series focuses on minimizing external component count while maintaining high performance in transmit paths.
