Description

The LTM9004 is a 14-bit direct conversion receiver subsystem. Utilizing an integrated system in a package (SiP) technology, the LTM9004 is a μModule® receiver that includes a dual high speed 14-bit A/D converter, lowpass filter, differential gain stages and a quadrature demodulator. Contact Analog Devices regarding customization.The LTM9004 is perfect for zero-IF communications applications, with AC performance that includes 76dB SNR and 63.5dB spurious free dynamic range (SFDR). The entire chain is DC-coupled and provides access for DC offset adjustment. The integrated on-chip broadband transformers provide 50Ω single-ended interfaces at the RF and LO inputs.A 5V supply powers the mixer and first amplifier for minimal distortion while a 3V supply allows low power ADC operation. A separate supply allows the outputs to drive 0.5V to 3.3V logic. An optional multiplexer allows both channels to share a digital output bus. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.Applications Telecommunications Direct Conversion Receivers Cellular Basestations
