Monolithic Linear IC
LA1888NM
C g r S t e r e o single-Chip Tuner IC
Overview
The LAI888NM is a high-performance, multi-function
single-chip luner IC that was developed for use in car
stereo systems. The LAI888NM is a second-generation
singlc-chip tuner IC that integrates six blocks in a single
package. Five of those blocks provide performance and
functional improvements over the corresponding five
blocks provided by the first-generation LA1886M and
LA1883M, white the additional sixth Nock consists of an
MRC circuit that reduces the noise in multipath reception.
Functions
• FM from end, FM IF, noise canceller, multiplex, MRC
(multipath rejection circuit), AM, and FM/AM
switching. (See the following page for details.)
Features
• A tuner's characteristics are determined by the noise
suppression performance. The most significant feature
of the LAI888NM is that the characteristics of the
individual blocks have been redesigned to improve the
noise characteristics in the cases of multipath, three
signal IM, two signal suppression and AM interference.
• Excellent anti-three signal interference characteristics,
equivalent to those of the LAI I93M FM front end (3D
AGC system).
• Improved noise canceler characteristics in the medium
and weak field of antenna input signals.
• Improved stereo separation (excellent high frequency
separation)
• Built-in anti-birdie filter (f = 114 kHz, 190 kHz)
* Built-in MRC circuit that detects multipath noise
* The W-AGC sensitivity, which is essentially equivalent
(o that of the LAI I37N, was increased by 10 dB (from
95 dB^j to 85 dBp) during seek operations to prevent
stopping at spurious stations with strong interference.
* The AM detector output frequency characteristics can
be set independently.
(Low frequency and high frequency A F responses can
be set independently.)
• The pin layout of the first-generation LAI883M single-
chip products has been maintained, thus casing
transition and supporting product miniaturization.
• Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft's
control systems, or other applications whose failure can be reasonably expected to result In serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein In such applications.
• SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.
