Overview
The LA8604M is a narrowband FM IF stage IC that incorporates all the functional blocks for a complete IF stage,
including noise filtering, making it ideal for use in cordless
telephones.
The LA8604M comprises a second-stage oscillator, a mixer ,
an IF amplifier, an FM detector, and noise detector , amplifier and rectifier circuits. A signal level meter output which
is linear over a wide dynamic range of up to 70dB is also
incorporated.
The LA8604M operates from a 2.4 to 6V supply and is
available in 24-pin MFPs.
Features
• On-chip mixer, IF amplifier and limiter.
• On-chip noise filter buffer.
• 70dB (typ) signal level meter linearity.
• Signal level meter output buffer.
• 2.4 to 6V supply.
• 24-pin MFP.
