Receiver subsystems connected to RF and digital world

Linglier-launched a system-on-package (SiP) signaling link receiver module series of first products LTM9001, this series offers a linglier-micro module (μ M o d u l e T M) packaging technology, specially designed for connecting RF and digital areas.

LTM9001 is a can-customized IF/baseband receiver subsystems, including sampling rate 160Msps 16-bit analog-to-digital converter (ADC), anti-aliasing filter and fixed gain differential ADC driver. In the RF applications on large dynamic range of signal sampling requires a wealth of experience to maximize the use of the full functionality of ADC. Need to be familiar with the amplifier output stage and ADC front-end knowledge to match impedance, also requires careful attention to layout to minimize the digital output to sensitive analog input coupling. In many cases, ADC performance degradation is often because the layout is not good. These factors may specialize in the field of RF or digital engineers bring challenges. Select the component LTM9001, input impedance matching, filter design and layout of the burden from designers there are transferred to the device. LTM9001 with half-customization (customization requires a minimum number of orders). Use pin-compatible family of products, the LTM9001 can for a variety of sampling rate and configuration, differential ADC driver can take up to 8dB-26dB fixed-gain versions. Anti-aliasing filter can also be configured to low-pass or band-pass filter, can accept the input frequency 300MHz. LTM9001 adopts 11.25mm x 11.25mm LGA packages, a multilayer substrate, it can put sensitive analog circuit and digital line. LGA pads on the bottom of the package so that you can enter and clock signal and digital output, thus simplifying the work of the layout designer. Bypass capacitor placement in module internal and close to the chip. LTM9001 without external capacitor, the footprint is about implementation of discrete components. LTM9001 has now started a bulk supplier to 1,000 tablets for the bulk purchase, price per piece for $ 82.
