ISG2000DS  
5 V CATV MODEM RF TRANSCEIVER  
FEATURES  
DESCRIPTION AND APPLICATIONS  
The ISG2000DS is a complete RF transceiver designed for  
use in cable modem applications. The transceiver integrates  
a diplex filter, double conversion receiver and transmit AGC  
amplifier (see Figure 1). The diplex filter provides over 40 dB  
of isolation between the TX band and the RX band. The  
receiver converts QAM signals in the RX band down to the IF  
sampling frequency and provides the necessary gain control  
input power to the DSP. The RF transmitter section provides  
40 dB gain control under all conditions, while maintaining  
excellent linearity performance.  
• TWO WAY MCNS COMPLIANT:  
91-860 MHz Downstream  
5-42 MHz Upstream  
• INTERFACES DIRECTLY WITH QAM DEMOD/MOD ICs  
• BUILT IN RF TRANSMITTER:  
50 dB AGC Driver  
• LOW PHASE NOISE:  
-85 dBc/Hz @ 10 KHz  
• BUSINESS CARD SIZE:  
3.4" x 2.0" x 0.5"  
• RUGGED/NO MICROPHONICS:  
All SMD Components, "Coiless"  
• EUROPEAN AND US VERSIONS AVAILABLE  
• LOW POWER CONSUMPTION:  
RX: 1.2 Watts, TX: 0.6 Watts
