GENERAL DESCRIPTION  
or to an internal low distortion current amplifier. The current  
amplifier (IAMP) can be configured as a current or voltage  
mode line driver (with two external npn transistors) capable of  
delivering in excess of 23 dBm peak signal power. Tx power can  
be digitally controlled over a 19.5 dB range in 0.5 dB steps.  
The AD9866 is a mixed-signal front end (MxFE) IC for  
transceiver applications requiring Tx and Rx path functionality  
with data rates up to 80 MSPS. Its flexible digital interface,  
power saving modes, and high Tx-to-Rx isolation make it well  
suited for half- and full-duplex applications. The digital inter-  
face is extremely flexible allowing simple interfaces to digital  
back ends that support half- or full-duplex data transfers, thus  
often allowing the AD9866 to replace discrete ADC and DAC  
solutions. Power saving modes include the ability to reduce  
power consumption of individual functional blocks or to power  
down unused blocks in half-duplex applications. A serial port  
interface (SPI®) allows software programming of the various  
functional blocks. An on-chip PLL clock multiplier and  
synthesizer provide all the required internal clocks, as well as  
two external clocks from a single crystal or clock source.  
The receive path consists of a programmable amplifier  
(RxPGA), a tunable low pass filter (LPF), and a 12-bit ADC. The  
low noise RxPGA has a programmable gain range of −12 dB to  
+48 dB in 1 dB steps. Its input referred noise is less than  
3.3 nV/rtHz for gain settings beyond 30 dB. The receive path  
LPF cutoff frequency can either be set over a 15 MHz to  
35 MHz range or simply bypassed. The 12-bit ADC achieves  
excellent dynamic performance over a 5 MSPS to 80 MSPS  
span. Both the RxPGA and the ADC offer scalable power  
consumption allowing power/performance optimization.  
The Tx signal path consists of a bypassable 2×/4× low-pass  
interpolation filter, a 12-bit TxDAC, and a line driver. The  
transmit path signal bandwidth can be as high as 34 MHz at an  
input data rate of 80 MSPS. The TxDAC provides differential  
current outputs that can be steered directly to an external load  
The AD9866 provides a highly integrated solution for many  
broadband modems. It is available in a space-saving 64-lead  
chip scale package and is specified over the commercial (−40°C  
to +85°C) temperature range.
