Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd. provides customers with 1Gsps, multi-channel high-speed ADC HMCAD1511 analog-to-digital converter products.

Introduction

The HMCAD1511 is a versatile, high-performance, low-power analog-to-digital converter (ADC) that uses time-interleaved technology to improve sampling rates. The integrated crosspoint switch activates user-selected inputs.

In single-channel mode, the HMCAD1511 can select one of four inputs as a valid input for a single ADC channel. In dual-channel mode, the HMCAD1511 can select any two of the four inputs for each ADC channel. In four-channel mode, any HMCAD1511 input can be assigned to any ADC channel.

Based on a patented structure, the HMCAD1511 uses an internal reference voltage source circuit, serial control interface and serial LVDS/RS DS output data. The data and frame synchronization clock is used for data capture by the receiver. With an ENOB greater than 7.5 (up to 16X gain) for internal 1 to 50X digital coarse tuning gain, oscilloscope gain setting can be achieved digitally. The internal digital fine-tuned gain can be set individually for each ADC to calibrate the gain error.

The HMCAD1511 is designed to easily interface with field programmable gate arrays (FPgas) from multiple vendors.
