LTM9001-GA

LTM9001-GA 16-Bit IF/Baseband Receiver Subsystem FeaTures n n DescripTion The LTM®9001 is an integrated System in a Package (SiP) that includes a high-speed 16-bit A/D converter, matching network, anti-aliasing filter and a low noise, differential amplifier with fixed gain. It is designed for digitizing wide dynamic range signals with an intermediate frequency (IF) range up to 300MHz. The amplifier allows either AC- or DCcoupled input drive. A lowpass or bandpass filter network can be implemented with various bandwidths. Contact Linear Technology regarding semi-custom configurations, (see Table 1.) The LTM9001 is perfect for IF receivers in demanding communications applications, with AC performance that includes 78dBFS noise floor and 87dB spurious free dynamic range (SFDR) at 5MHz (LTM9001-GA). The digital outputs are single-ended CMOS. A separate output power supply allows the CMOS output swing to range from 0.5V to 3.3V. An optional clock duty cycle stabilizer allows high performance at full speed with a wide range of clock duty cycles.
