The LTM9002 is a 14-bit, dual channel IF receiver subsystem. The device utilizes an integrated system-in-package (SiP) technology that includes a dual-channel high-speed 14-bit A/D converter (analog-to-digital converter, or A/D converter, or ADC for short, usually refers to a conversion of analog signals) Electronic components for digital signals), matching networks, anti-aliasing filters (anti-alias filter anti-alias filter is a low-pass filter to reduce the aliasing frequency component to a negligible level in the output level And two low noise, differential amplifiers. It is designed for digitizing wide dynamic range signals with up to 300MHz intermediate frequency (IF).
The LTM9002 is ideal for demanding communications applications with AC performance including 66dB SNR and 76dB spurious free dynamic range. A single 3V power supply enables low power operation. A separate output supply allows the output to drive 0.5V to 3.3V logic. The two single-ended CLK inputs can be driven together or independently.
LTM9002 features: integrated dual-channel, 14-bit, high-speed ADC, passive filter and fixed gain differential amplifier (a circuit that amplifies the difference between two input voltages, also known as a differential amplifier. This is a zero drift Small direct-coupled amplifiers, commonly used for DC amplification): up to 300MHz IF range; low pass and bandpass filter versions; integrated low noise, low distortion amplifier; fixed gain: 8dB, 14dB, 20dB or 26dB; 50Ω, 200Ω or 400Ω input Integrated bypass capacitors eliminate the need for external components; achieve 66dB SNR (LTM9002-AA) at input frequencies up to 140MHz; 76dB SFDR (LTM9002-AA) at input frequencies up to 140MHz; aid for gain adjustment 12-bit DAC; clock duty cycle stabilizer; single 3V to 3.3V supply; low power: 1.3W (665mW per channel); shutdown and hiccup mode; 5mm x 11.25mm LGA package.
