Typical Application
Description
The LTM9001 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 DC-coupled input drive. A lowpass or bandpass filter network can be implemented with various bandwidths. Contact Linear Technology regarding semi-custom configurations.
The LTM9001 is perfect for IF receivers in demanding communications applications, with AC performance that includes 72dBFS noise floor and 82dB spurious free dynamic range (SFDR) at 162.5MHz (LTM9001-AA).
The digital outputs can be either differential LVDS or single ended CMOS. There are two format options for the CMOS outputs: a single bus running at the full data rate or two demultiplexed buses running at half data rate. A separate output power supply allows the CMOS output swing to range from 0.5V to 3.3V.
The differential ENC+ and ENC– inputs may be driven with a sine wave, PECL, LVDS, TTL or CMOS inputs. An optional clock duty cycle stabilizer allows high performance at full speed with a wide range of clock duty cycles.
