ADS58C48IPFP Quad 11-bit 200MSPS ADC with SNRBoost Imported Original Genuine In Stock-Yujixin Electronics

describe

The ADS58C48 is a quad-channel 11-bit A/D converter with sampling rates up to 200 msps. It uses innovative design techniques to achieve high dynamic performance while consuming extremely low power from a 1.8V supply. This makes it ideal for multi-carrier, broadband communications applications.

The ADS58C48 uses the third-generation SNRBoost3G technology to overcome quantization noise (bandwidth

The device features a digital gain function that can be used to improve sfdr performance at lower full-scale input ranges. It includes a dc offset correction loop that can be used to cancel a dc offset.

The digital outputs of all channels are DDR LVDS (Double Data Rate) and LVDS clock outputs. The interface's low data rate (400mbps at 200msps sample rate) makes it possible to use low-cost FPGA-based receivers. The strength of the LVDS output buffer can be increased to support 50 ohm differential termination. This allows the output clock signal to be connected to two separate receiver chips with effective 50 terminations (eg the two clock ports of the gc5330).

The same digital output pins can also be configured as a parallel 1.8V CMOS interface.

It includes an internal reference, while the traditional reference pins and associated decoupling capacitors have been eliminated. The unit is specified over the industrial temperature range (–40°C to 85°C).
