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 Analog Devices 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.ApplicationsTelecommunicationsHigh Sensitivity ReceiversCellular Base StationsSpectrum Analyzers
