Description
The SL1935 is a complete single chip
bus controlled Zero IF tuner and operates from 950 to 2150MHz.
It includes an on-board low phase noise PLL frequency
synthesiser and low noise LNA/AGC. The SL1935 is
intended primarily for application in digital satellite Network
Interface Modules and performs the complete tuner
function.
The device contains all elements necessary, with the
exception of local oscillator tuning network and crystal
reference, to produce a high performance I(n-phase) &
Q(uadrature) downconversion tuner function. Due to the
high signal handling design the device does not require
any front end tracking filters.
The SL1935 includes selectable baseband signal paths,
allowing application with two externally definable filter
bandwidths, facilitating application in variable symbol
rate and simulcast systems. The SL1935 is optimised to
interface with the VP310 (ADC/QPSK/FEC) Satellite
Channel Decoder, available from Zarlink Semiconductor
and offers a full front end solution.
Features
Single chip synthesised tuner solution for quadrature
down conversion, L-band to Zero IF.
DVB compliant, operating dynamic range -70 to
-20dBm.
Compatible with DSS and DVB variable symbol rate
applications.
Selectable baseband path, programmable through
I²C bus.
Excellent quadrature balance up to 30MHz
baseband
Excellent immunity to spurious second harmonic
(RF and LO) mixing effects.
Low oscillator phase noise and reradiation.
High output referred linearity for low distortion and
multi channel application.
Integral fast mode compliant I²C bus controlled PLL
frequency synthesiser, designed for high comparison
frequencies and low phase noise performance.
Buffered crystal output for clocking QPSK
demodulator.
ESD protection (Normal ESD handling procedures
should be observed).
Applications
Satellite receiver systems.
Data communications systems.

PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large ‘Milspec’ Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however pristine, stored with us still in their original packaging and ‘as new’ in all respects, the photographs are representative of their excellent condition, and, as with all our products they come with a full guarantee.If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
