0 DS3842 - 4.
1 March 1997 The SL1710 is a quadrature downconverter, intended for use with both Professional and Consumer Digital Satellite Applications.
The device contains high linearity, low noise amplifiers, quadrature mixers, plus an on-chip oscillator, operating between 350MHz and 500MHz, which may be synthesised via the differential prescaler outputs.
An AGC with 18dB gain control is provided to cope with a wide range of input signal levels.
I and Q outputs are via low impedance single ended amplifiers.
These may be connected to a dual channel analog to digital converter such as the PCA916, VP216, VP215 or VP213, via a suitable anti-alias filter.
