Overview
The LA8670M is a narrow band FM IF system for use in communication equipment. In addition to the functions required for FM reception, the LA8670M provides a rich set of additional functions including noise detection and field strength detection, and is thus optimal for cordless telephones.

Functions
• First mixer, first local oscillator, first local oscillator buffer output, second mixer, second local oscillator
• IF amplifier, limiter, quadrature detector
• Signal meter
• Noise detector, noise amplifier, noise wave detector, Schmitt trigger

FEATUREs
• Low voltage operation: VCC OP = 1.8 to 6 V
• Signal meter linear over a wide range (70 dB typical)
• High sensitivity, high intercept point
