The LTM9002 is a 14-bit dual-channel IF receiver subsystem. Utilizing an integrated system in a package (SiP) technology, it includes a dual high-speed 14-bit A/D converter, matching network, anti-aliasing filter and two low noise, differential amplifiers. It is designed for digitizing wide dynamic range signals with an intermediate frequency (IF) up to 300MHz. The amplifiers allow either AC- or DCcoupled input drive. Lowpass or bandpass filter networks can be implemented with various bandwidths. Contact Analog Devices regarding customization.
The LTM9002 is perfect for demanding communications applications, with AC performance that includes 66dB SNR and 76dB spurious free dynamic range (SFDR). Auxiliary DACs allow gain balancing between channels.
A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.3V logic. An optional multiplexer allows both channels to share a digital output bus. Two single-ended CLK inputs can be driven together or independently. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.
