Digital Receiver Front-end
Release Note: Revision bars indicate significant
changes to the previous edition.
1. Introduction
The Digital Receiver Front-end DRX 3960A performs
the entire multistandard Quasi Split Sound (QSS) TV
IF processing, AGC, video demodulation, and genera-
tion of the second sound IF (SIF) with only one SAW
filter. The IC is designed for applications in TV sets,
VCRs, PC cards, and TV tuners.
The alignment-free DRX 3960A needs no special
external components. All control functions and status
registers are accessible via I
2
C bus interface. There-
fore, it simplifies the design of high-quality, highly stan-
dardized IF stages.
Due to its mixed signal structure and the digital
demodulation, the IC offers unique features and is pre-
pared for digital TV.
1.1. Features
–
Multistandard QSS IF processing with a single SAW
–
Highly reduced amount of external components (no
tank circuit, no potentiometers, no SAW switching)
–
Programmable IF frequency
(38.9 MHz, 45.75 MHz, 32.9 MHz, 36.125 MHz etc.)
–
Digital IF processing for the following standards:
B/G, D/K, I, L/L
’
, and M/N
–
Standard specific digital post filtering
–
Standard specific digital video/audio splitting
–
Standard specific digital picture carrier recovery:
alignment-free
quartz-stable and accurate
stable frequency lock at 100% modulation and
overmodulation up to 150%
quartz-accurate AFC information
–
Programmable standard specific digital group delay
equalizing
–
Automatically frequency-adjusted Nyquist slope,
therefore optimal picture and sound performance
over complete lock in frequency range
–
Standard-specific digital AGC and delayed tuner
AGC with programmable tuner Take Over Point
–
Fast AGC due to linear structure
–
Adaptive back porch control, therefore fast positive
modulation AGC
–
No sound traps needed at video output
–
Second SIF output with standard dependent pre-fil-
tering and amplitude controlled output level
–
Optimal sound SNR due to carrier recovery without
quadrature distortions
–
FM radio capability without external components
and with standard TV tuner
–
Prepared for digital TV (DVB-C, DVB-T, ATSC)
