ADC1207S080HW/C1,5

Analog To Digital Converters (ADC) Overview

The ADC1207S080 is a single 12-bit Analog-to-Digital Converter (ADC) optimized for direct Input Frequency (IF) sampling in ultra-high IF radio transceivers. It operates at a maximum sampling rate of 80 MHz with a differential input bandwidth of 375 MHz. The device features an internal front-end buffer providing less than 1 pF input capacitance, enabling flexible aliasing filter strategies. It supports full-scale adjustment from 1.5 V to 2 V peak-to-peak and utilizes a single 5 V analog/digital supply alongside a 3.3 V LVCMOS output supply. Key performance metrics include 90 dB SFDR at 225 MHz input frequency and 74 dB SFDR at 175 MHz.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type HTQFP48 (SOT545-2) matches design requirements. Confirm supply voltage conditions: VCCA/VCCD at 5.0 V nominal and VCCO at 3.3 V nominal. Ensure thermal management accounts for total power dissipation up to 990 mW at maximum clock rates. Check for industrial temperature range compliance (-40 °C to +85 °C).

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring direct high-frequency IF sampling without intermediate mixing stages. The low input capacitance (< 1 pF) simplifies front-end filter design. Ensure the system can provide stable 5 V analog/digital supplies and 3.3 V logic levels. Consider the 2-cycle latency and programmable CCS delay for precise data acquisition timing alignment.

Analog To Digital Converters (ADC) FAQ

How is the full-scale input voltage adjusted?

The full-scale input voltage is continuously adjustable from 1.5 V to 2 V peak-to-peak by connecting an external reference voltage to the FSIN pin.

What clock modes are supported?

The ADC supports PECL mode 1, PECL mode 2, PECL mode 3, Differential AC driving mode, and TTL mode, allowing flexibility in clock source integration.

What is the function of the CCS pin?

The Complete Conversion Signal (CCS) is a programmable output that indicates when conversion is complete. Its delay can be adjusted using DEL0 and DEL1 inputs to optimize data acquisition timing.
