Description

[ /Title

(CA31

89)

• Includes IF Ampliﬁer, Quadrature Detector, AF The Harris CA3189E is a monolithic integrated circuit that

Preampliﬁer, and Speciﬁc Circuits for AGC, AFC, Tun- provides all the functions of a comprehensive FM-lF system.

ing Meter, Deviation-Noise Muting, and ON Channel The block diagram of the CA3189E includes a three-stage

Detector

FM-lF ampliﬁer/limiter conﬁguration with level detectors for

each stage, a doubly-balanced quadrature FM detector and

an audio ampliﬁer that features the optional use of a muting

(squelch) circuit.

• FM IF Ampliﬁer Applications in High-Fidelity,

Automotive, and Communications Receivers

• Exceptional Limiting Sensitivity -12µV (Typ) at -3dB

Point

The advanced circuit design of the IF system includes desir-

able deluxe features such as programmable delayed AGC

for the RF tuner, an AFC drive circuit, and an output signal to

drive a tuning meter and/or provide stereo switching logic. In

addition, internal power-supply regulators maintain a nearly

constant current drain over the voltage supply range of

+8.5V to +16V.

• Low Distortion -0.1% (Typ) (with Double-Tuned Coil)

• Single-Coil Tuning Capability

• Improved S + N/N Ratio

• Externally Programmable Recovered Audio Level

• Provides Speciﬁc Signal for Control of Interchannel

Muting (Squelch)

The CA3189E is ideal for high-ﬁdelity operation. Distortion in

a CA3189E FM-lF System is primarily a function of the

phase linearity characteristic of the outboard detector coil.

The CA3189E has all the features of the CA3089E plus addi-

tions. See CA3189E features compared to the CA3089E in

Table 1.

• Provides Speciﬁc Signal for Direct Drive of a Tuning

Meter

• On Channel Step for Search Control

• Provides Programmable AGC Voltage for RF Ampliﬁer

• Provides a Speciﬁc Circuit for Flexible Audio Output

• Internal Supply Voltage Regulators
