IP Cores

1Msps, 18bit SAR ADC

eyADC-SI2 is a dual channel differential analog-to-digital converters (ADCs) based on successive approximation (SAR) with high accuracy (18 bit) and a sampling rate of up to 1 MSPS.

 

The reference voltage is generated on chip and only requires one external capacitor. eyADCSI2 also provides an input common mode voltage source to set the common mode for reference free signal sources. Both the reference and the common mode voltage source requires very little power keeping the quiescent power consumption at only 50 μW.

 

The ADC itself consumes no power during sampling (zero power sampling). Therefore, its power consumption scales linearly with the conversion rate only requiring 230 μW at 64 kSPS.

8GSPS, 12bit ADC

A 12-bit monolithic sampling analog-to-digital converter (ADC) that operates at conversion rates of up to 8 giga samples per second (GSPS). This product is designed for sampling wide bandwidth analog signals up to 4 GHz. The combination of wide input bandwidth, high sampling rate, and excellent linearity of the ADC is ideally suited for spectrum analyzers, data acquisition systems, and a wide assortment of military electronics applications, such as radar and electronic countermeasures.

 

The JESD204B-based high speed serialized output uses 8 lanes with 16 Gbit/s. The product is specified over the industrial temperature range of −40°C to +85°C.

 

Specifications:
– Sample rate 8 GS/s
– SFDR 72dB
– SNR 54dB
– Differential input 100 Ohm
– FSR 1V
– Time-interleaved 18 SAR-ADC
– Internal Reference
– Data output: JESD204B, 8 Lanes á 16Gbit/s
– Power consumption <4W

UV-LED Driver

The eyIC4UV-01 is a universal digitally regulated high precision PWM-enabled LED control chip. The LED regulated current is continuously monitored inside a current sensing feedback loop, enabling the eyIC4UV-01 to drive just one or a chain of sequentially connected LEDs. The eyIC4UV-01 provides internal driver circuitry, which supports LED forward voltages up to 15V. For higher LED forward voltages of up to 200V (such as when several LEDs must be connected in a chain), the chip provides control signals for the external driver which, depending on the number of the LEDs must supply the corresponding LED forward voltage.

 

To optimize the loop control and stability and therefore, precisely regulating the LED current, the LED temperature, its light intensity, and its supplied current are continuously monitored and configured to set the optimal PWM duty cycle. This PWM duty cycle is then used to adjust the LED current. In an alternative setting the LED current can also be controlled using a linear regulator. Both the linear regulator and the PWM modulator are driven digitally through a DAC. Both control mechanisms can be utilized to regulate the LED current, depending on the specific application requirements.

 

Users have the option to control the LED current using either a digital SPI interface or by providing external analog input signals.

500V galvanic isolation

The eyICL8P is an eight channel, digital-input interface device for high channel density modules in industrial and building automation. The input side does not require an external power supply. The device accepts input voltages of up to 35 Volt. It includes a galvanic isolation up to 500 Volt. The device completes the interface between the high voltage signals on the field-side and the low-voltage signals on the controller side. Input signals are current limited and validated by an internal debounce filter. With the addition of an external resistor the input switching characteristic can be configured in accordance with IEC61131-2 standard for Type 1, 2 and 3 current inputs.

Digitally controlled frequency synthesizer for 24GHz radar

eyRF-S12 is a fully integrated frequency synthesizer for FMCW radar applications. Since it is based on an all-digital Phase Locked Loop no external loop filter is necessary. Instead, the loop bandwidth can be controlled and optimized via a digital interface. This, and the fact that oscillator and feedback loop are already implemented together in an integrated solution offers a time saving and area efficient possibility for the development of radar systems. The Time-to-Digital Converter (TDC) is adapted for the Digitally Controlled Oscillator (DCO) and offers very low closed loop phase noise. An integrated calibration algorithm enables highly linear and fast FMCW ramps.

4GHz Impulse-Radio Ultra-Wideband Transceiver

The eyRF-T5 is a fully integrated transceiver operating within in the scope of IEEE 802.15.6 WBAN and employing the ultra-wideband physical layer. Because of the employed pulsed signals with 500 MHz of bandwidth, the signal power levels are in the order of those used in the MICS band, therefore providing safe power levels for the human body and low interference to other devices. All three frequency channels 3.494, 3.993 and 4.492 GHz are supported with data rates from 0.487 up to 15.6 Mbps. The transceiver total power consumption may be reduced to 10 mW.

 

The included digital channel coding blocks offer forward error correction and AES-128 encryption to increase robustness and security.
