The MC145406D is a low-cost, highly integrated monolithic direct broadcast satellite (DBS) tuner having excellent performance and features. This product is ideally suited for DBS systems that require excellent receive sensitivity and linearity and for cable systems requiring limited signal strength control. This product also features an intermediate frequency (IF) output and a buffered IF and low-noise amplifier (LNA) input.

The MC145406D is designed to cover a wide range of digital and analog terrestrial and cable broadcast applications. It allows integration of key broadcast receiverfront end components into one IC. These componentsinclude a PLL-based tuner IC, a wide range of low and high frequency filters, and a low noise amplifier with adjustable gain and dynamic range.

The MC145406D is a high performance, low cost, highly integrated monolithic direct broadcast satellite (DBS) tuner. The MC145406D features an IF input stage that buffers the IF signal and provides a low-noise amplifier (LNA) input. It also features a wide range of low and high frequency filters to reduce crosstalk and distortion in the receive signal.

The MC145406D chip is designed to cover a wide range of digital and analog terrestrial and cable broadcast applications. It employs a phase-locked loop (PLL) based architecture to achieve precise tuning and allows integration of key broadcast receiver front-end components into one IC, such as highly linear key filters, a buffer IF stage, and a low noise amplifier with adjustable gain. It also provides high output levels and allows two or more stages of IF amplifier to be used in combination with a buffered IF input.

The MC145406D can be used for digital and analog terrestrial and cable broadcast receiver applications. It has a fast PLL tuning circuitry for scanning and frequency agile applications. It also provides a selectable low-noise amplifier (LNA) with adjustable gain and an IF filter with very low in-channel distortion.

The MC145406D is also designed to operate in combination with a preamplifier, allowing the system designer to take advantage of low-cost off-the-shelf active monolithic components. This feature reduces development costs and offers enhanced sensitivities. The MC145406D provides more than 20dB of gain in the IF amplifier stage, which makes it extremely beneficial for cable and DBS systems requiring low signal strength control.

The MC145406D is designed to interface with various analog-to-digital and digital-to-analog converters. The output can also be processed before feeding the demodulator. This allows for a variety of applications, from digital satellite receivers to standard television reception applications.

In summary, the MC145406D is an ideal tool for digital and analog terrestrial and cable broadcast applications requiring excellent performance with high integration. This product allows for the integration of key broadcast receiver front-end components into one IC, with excellent receive sensitivity and linearity, low distortion levels, and adjustable gain and dynamic range. The MC145406D can be used in combination with a preamplifier and is ideal for cable and DBS systems that require low signal strength control.
