SL1935
Single Chip Synthesized Zero IF Tuner
Preliminary Information
Description
The SL1935 is a complete single chip
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.

C
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 Mitel Semiconductor
and offers a full front end solution.
