Targeting broadband data applications such as 5G communications and radar, RuiMeng Technology introduces the MS5134: a dual-channel, 14-bit, 125MSPS, serial LVDS, 1.8V analog-to-digital converter. Leveraging excellent dynamic performance, low-power design, and a flexible serial LVDS interface, this product provides a high cost-performance solution for related systems.

Core Advantages

01 High-Speed, High Fidelity, Cleaner Signal

The MS5134 integrates an on-chip sample-and-hold circuit, supporting a maximum conversion rate of 125MSPS with outstanding dynamic performance:

  • SNR: 67.1dBFS

  • SFDR: 75.5dBc

  • DNL: ±0.7 LSB

  • INL: ±10 LSB

These specifications allow the MS5134 to maintain very high fidelity when processing high-speed signals, meeting the stringent signal integrity requirements of applications such as I/Q demodulation and smart antennas.

02 Low-Power Design: Flexible and Efficient

The chip operates from a single 1.8V supply. At a 125MSPS sample rate, the dual-channel MS5134 consumes only 245mW and supports power adjustment options, allowing engineers to balance power consumption and performance. This feature is highly significant for power-sensitive systems such as portable communication equipment or high-density boards.

03 Interface and Clock: Simplifying System Design

The MS5134 fully considers system integration convenience in its interface design:

  • Serial LVDS Output: Default compatible with the ANSI-644 standard, with an optional reduced range, effectively reducing the number of data lines and simplifying PCB layout.

  • Flexible Clock Input: Compatible with various sampling clock signals such as LVPECL/CMOS/LVDS, adapting to different signal sources.

  • Automatic Clock Multiplication: Built-in clock multiplication function that automatically adjusts the LVDS serial data rate d on the sampling rate.

Additionally, the chip provides a data clock output (DCO) and a frame clock output (FCO). The DCO operates up to 500MHz and is used for precise data capture at the output end; the FCO identifies new output bytes, significantly simplifying digital interface design.

Application Scenarios

Communication Systems: In communication applications such as 4G/5G stations, I/Q demodulation systems, and smart antennas, the MS5134's 67.1dBFS SNR and 75.5dBc SFDR enable accurate recovery of weak signals in complex electromagnetic environments, effectively reducing bit error rates. The dual-channel design supports simultaneous I/Q sampling, ensuring phase consistency and simplifying algorithms such as Digital Pre-Distortion (DPD). Furthermore, the dual-channel power consumption of only 245mW significantly reduces thermal management pressure in remote radio units, facilitating high-density board integration.

Radar Systems: In radar, electronic warfare, and phased-array systems, the MS5134's high sample rate of 125MSPS and 14-bit resolution allow precise capture of narrow pulse echo details, markedly improving range resolution. Its excellent linearity effectively suppresses spurious targets and harmonic interference, ensuring target identification accuracy. The serial LVDS interface greatly reduces the number of data lines, making it particularly suitable for array systems with multi-channel synchronous sampling, simplifying PCB layout and improving signal integrity.

The MS5134 dual-channel ADC and its family product MS5133 provide an ideal analog-to-digital conversion solution for high-performance applications such as communications and radar, featuring high sample rate, high performance, low power consumption, and a flexible interface design.
