NXP Semiconductors ADC1207S080HW/C1:1

Overview

ADC1207S080HW/C1:1 from NXP Semiconductors is a 12-bit, 80 MHz sampling-rate analog-to-digital converter optimized for ultra-high IF radio transceivers in cellular infrastructure. It features differential 375 MHz input bandwidth, <1 pF input capacitance, 90 dB SFDR at 225 MHz input, and programmable Complete Conversion Signal (CCS) with sub-nanosecond delay control. It operates from a single 5 V analog/digital supply and delivers LVCMOS-compatible 12-bit parallel outputs for direct interface to FPGA or ASIC baseband processors.

For engineers reviewing the ADC1207S080HW/C1:1 datasheet, ADC1207S080HW/C1:1 pinout, ADC1207S080HW/C1:1 application, or ADC1207S080HW/C1:1 equivalent, key selection criteria include its ultra-low input capacitance for flexible anti-aliasing filter design, dual-mode output coding (binary/two's complement), CCS programmability for timing alignment in high-speed data acquisition, and validated performance in multi-carrier W-CDMA and LTE receiver front-ends.

Technical Context

The ADC1207S080HW/C1:1 employs a track-and-hold architecture with internal front-end buffer to achieve <1 pF input capacitance and 375 MHz analog bandwidth. Its differential input stage supports PECL, TTL, and AC-coupled clock modes with configurable edge-sampling logic on CLK/CLKN inputs.

Conversion timing is governed by a fixed 2-cycle latency pipeline, and output data validity is synchronized via the programmable CCS signal-delayed using DEL0/DEL1 pins to align with external logic setup/hold windows. Full-scale range is adjustable from 1.5 V to 2.0 V_p-p via FSIN reference voltage input.

FAQ

What is the maximum analog input frequency supported by the ADC1207S080HW/C1:1?

The ADC1207S080HW/C1:1 supports analog input frequencies up to 400 MHz, as confirmed in the application information section for 3G radio receivers. This capability enables direct undersampling of ultra-high IF signals such as 350 MHz in cellular infrastructure applications while maintaining 65 dB SNR and 71 dBc SFDR performance.

How does the programmable Complete Conversion Signal (CCS) function in the ADC1207S080HW/C1:1?

The ADC1207S080HW/C1:1 generates a CCS output that indicates valid data availability after conversion. DEL0 and DEL1 pins select one of three delay states (0.3 ns, 1.3 ns, or 2.3 ns typical) to align the CCS edge precisely within the stable window of D0–D11 outputs-critical for reliable latching in high-speed FPGA interfaces without added timing margin.

Can the ADC1207S080HW/C1:1 operate with a single 3.3 V supply?

No, the ADC1207S080HW/C1:1 requires separate 5 V analog/digital supplies (VCCA and VCCD = 4.75–5.25 V) and a 3.3 V output supply (VCCO = 2.7–3.6 V). The 5 V rails power the analog core and digital logic, while VCCO exclusively powers the LVCMOS output drivers-ensuring signal integrity and noise isolation between domains.

What is the significance of the <1 pF input capacitance specification for the ADC1207S080HW/C1:1?

The <1 pF input capacitance of the ADC1207S080HW/C1:1 drastically reduces reactive loading on preceding anti-aliasing filters and baluns, preserving passband flatness and enabling steeper roll-off designs without complex compensation. This allows simplified front-end architectures in multi-carrier systems where filter group delay variation must be minimized.

Does the ADC1207S080HW/C1:1 support both binary and two's-complement output formats?

Yes, the ADC1207S080HW/C1:1 supports both output coding schemes. The OTC pin controls format selection: logic LOW enables binary output, and logic HIGH enables two's-complement. This flexibility allows direct interfacing with unsigned DSP cores or signed arithmetic units without external translation logic.
