LA7790M規(guī)格書詳情
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
? RF amplifier
? Varactor diode-based VCO
? Muting
? Electronic volume control
? Power-saving modes
? Switchable output frequency range
? Power supply voltage of 5 V (4.5 to 5.5 V)
