SL1925  
Satellite Zero IF QPSK Tuner IC  
Preliminary Information  
DS4955  
ISSUE 3.1  
October 2001  
Features  
Ordering Information  
SL1925/KG/NP2S (Tubes)  
SL1925/KG/NP2T (Tape and Reel)  
Single chip system for direct quadrature down  
conversion from L-band  
High signal handling capability for minimum  
external component count application, requires  
external RF AGC of 30dB  
Compatible with DSS and DVB system  
requirements  
Excellent gain and phase match up to 30MHz  
baseband  
High output referred linearity for low distortion and  
multi channel application  
Fully balanced low radiation design  
Integral RF AGC amplifier  
Two selectable varactor tuned local oscillators  
with buffered output for driving external  
synthesiser loop  
Description  
TheSL1925isawidebandquadratureconverteroperating  
from 950 to 2150 MHz, intended primarily for application  
in satellite tuners.  
The device contains all elements necessary, with the  
exceptionoflocaloscillatorsustainingnetwork,tofabricate  
a high performance I(n-phase) & Q(uadrature) phase  
splitter and downconverter optimised for systems  
containing RF AGC gain control. The device allows for  
systems containing higher power analog interferers. For  
most applications RF tunable filtering is not essential.  
ESD protection (Normal ESD handling procedures  
should be observed)  
The SL1925 is optimised for use with a low phase noise  
synthesiser, a range of which are available from Zarlink  
Semiconductor. This will form a complete front end tuner  
functionfordigitalsatellitereceiversystemsutilisingDSP  
derotation recovery.  
Applications  
The device includes a very high signal handling front end  
with AGC, this provides for gain control, reference local  
oscillator with output buffer, phase splitter with I and Q  
mixers and baseband buffer amplifiers with external  
interstage filtering.
