DescripTion

14-Bit Direct Conversion

Receiver Subsystem

The LTM

9004 is a 14-bit direct conversion receiver sub-

system. 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 demodula-

tor. Contact Linear Technology 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.

A5V 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.
