Overview
The LA7790M is a QPSK data transmitter for digital cable
TV applications. By integrating the I/Q quadrature
modulator, RF amplifier, electronic volume control, mute
control, and other functions onto a single chip, parts count
is reduced and set size is miniaturized.
Features
Maximum RF amplifier output level of +10 dBm (75
terminator), suitable for directly driving the cable.
RF output frequency range of 5 to 70 MHz. Frequency
range selection function permits broadband designs.
Electronic volume control for direct-current control of
RF output level.
Muting ensures ample attenuation during periods with
no transmission.
Support for both internal and external bias for I/Q
modulation inputs.
Support for I/Q modulation frequencies up to 10 MHz.
(typ: 500 mVp-p)
Functions
I/Q quadrature modulator
I/Q input bias power supply
