HI5766KCA Overview
A pipelined ADC is a converter architecture that processes an analog input through multiple cascaded low-resolution stages, each stage resolving a few bits and passing a residual to the next stage. This allows much higher sampling rates than successive-approximation or flash architectures while consuming moderate power. Within the data-converter hierarchy, pipelined ADCs sit between high-speed flash ADCs and high-resolution sigma-delta ADCs, and are commonly deployed in communications, imaging, and instrumentation front ends.
Key features of the HI5766KCA include 10-bit resolution, 60 MSPS maximum sampling rate, single +5 V analog supply operation, CMOS-compatible digital outputs, internal sample-and-hold, and an analog input bandwidth that supports undersampling IF applications. The differential pipeline topology provides good common-mode noise rejection and stable dynamic performance over temperature. A single-ended or differential analog input can be driven, and the output data is presented as parallel CMOS words suitable for direct connection to an FPGA or DSP.
Typical applications include digital video processing, IF sampling in communication receivers, CCD imaging front ends, ultrasound beamforming, and general-purpose high-speed data acquisition. The wide input bandwidth allows the converter to be used in undersampling schemes where the input frequency exceeds half the sampling rate, a common technique in intermediate-frequency digitizers.
When designing with the HI5766KCA, ensure the analog input is driven with a low-impedance, bandwidth-matched amplifier and that the +5 V supply is well-decoupled close to the device. A/D converters running at 60 MSPS are sensitive to clock jitter; use a low-jitter crystal or PLL-derived clock source for best signal-to-noise ratio.

Typical Applications
HI5766KCA is suitable for 7 applications: IF Sampling in Communication Receivers, CCD Imaging Front End, Ultrasound Beamforming, High-Speed Data Acquisition Systems, Digital Video Processing, Portable Test and Measurement Instrumentation, Industrial Process Control and Automation.
IF Sampling in Communication Receivers
The HI5766KCA's 10-bit resolution at 60 MSPS suits IF sampling blocks in narrowband communication receivers where the intermediate frequency is 10-30 MHz. The fully differential pipelined front end rejects common-mode noise on the IF signal, while the wide analog input bandwidth supports undersampling architectures that eliminate an analog downconversion stage. Power dissipation of 260 mW at full speed keeps thermal budgets manageable in densely populated radio boards. The CMOS parallel outputs interface cleanly to an FPGA or DSP for channelization and demodulation downstream. Compared to a discrete flash ADC, the HI5766KCA integrates the sample-and-hold and reduces BOM count.
Recommended
CCD Imaging Front End
Digital still cameras and industrial line-scan imagers drive CCD outputs at pixel rates up to 50-60 MHz, which the HI5766KCA can capture with its 60 MSPS sampling rate and integrated sample-and-hold. The 10-bit resolution matches the dynamic range typical of consumer-grade CCD imagers and keeps downstream DSP load manageable. The CMOS parallel output bus drives a frame buffer or image processor directly, and the 28-SSOP package fits into the compact PCB layouts used in camera modules. For higher-end imagers, designers often migrate to 12-bit ADCs from the ADS8401 or ADS8406 families.
Recommended
Ultrasound Beamforming
Medical ultrasound systems digitize multiple receive channels at sample rates between 40 and 65 MSPS, making the HI5766KCA a viable front-end converter for mid-range portable scanners. The pipelined architecture provides the throughput needed to capture returning echoes at sufficient depth, while the 10-bit resolution is acceptable for B-mode display. Multiple HI5766KCA devices can be synchronized to a common clock for multi-channel beamforming arrays. Designers targeting premium systems typically migrate to 12-bit 65 MSPS converters such as the ADS5220 series for higher SNR.
Recommended
High-Speed Data Acquisition Systems
General-purpose 60 MSPS data acquisition cards digitize signals up to 30 MHz and stream the data to a host PC or DSP for analysis. The HI5766KCA's 60 MSPS conversion rate and parallel CMOS output are well matched to FPGA-based DAQ boards, where the FPGA buffers samples and forwards them over PCIe or USB. The differential analog input simplifies PCB layout and reduces ground-loop noise. For multi-channel DAQ systems, designers should consider the AD9220Q or ADS8508 from TI as alternate channels.
Recommended
Digital Video Processing
Standard-definition digital video (ITU-R BT.601) operates at 27 MSPS, while enhanced video and video capture applications often run at 54-65 MSPS per channel. The HI5766KCA can digitize composite or component video at 60 MSPS, providing 10-bit resolution suitable for studio and broadcast-quality processing. The pipelined architecture ensures low-latency conversion required by real-time video pipelines. The 28-SSOP footprint is convenient for video capture cards and PCI-based frame grabbers.
Recommended
Portable Test and Measurement Instrumentation
Handheld oscilloscopes and spectrum analyzers in the 60-100 MHz bandwidth class rely on 60 MSPS or higher ADCs to digitize the input signal. The HI5766KCA's 60 MSPS throughput and low 260 mW power consumption make it suitable for portable instruments where battery life matters. The CMOS outputs reduce interface power compared to LVDS parts and integrate easily with low-power FPGAs. For higher-bandwidth scopes, designers migrate to 100+ MSPS converters such as the ADS5424 series.
Recommended
Industrial Process Control and Automation
Industrial control loops that monitor high-speed vibration, motor current, or process variables benefit from 10-bit/60 MSPS conversion to capture transient events. The HI5766KCA's differential analog input rejects industrial common-mode noise from motor drives and switching power supplies. The 28-SSOP package is robust for industrial temperature ranges and surface-mount assembly. Industrial PLCs and machine-vision systems often use multiple HI5766KCA channels synchronized to a common clock for multi-axis monitoring.

Design Notes
The HI5766KCA's 60 MSPS sampling rate makes it sensitive to analog input drive impedance and clock jitter. Drive the analog input with a low-impedance, wideband op-amp (such as the THS4031 or AD8055) or a 1:1 transformer with 50 ohm source termination. Keep the analog input trace short and guarded by ground on both sides. Estimated: aperture jitter of 0.5 ps RMS will consume roughly 1 dB of SNR at 30 MHz input; use a clock source with sub-picosecond RMS jitter for full performance.
Estimated: at 60 MSPS with a +5 V analog supply, the HI5766KCA draws approximately 52 mA (260 mW). Decouple the analog and digital supplies separately with a 10 uF tantalum or ceramic bulk capacitor plus a 0.1 uF ceramic placed within 5 mm of each supply pin. Keep analog and digital ground planes joined at a single point under the converter to avoid ground-loop noise coupling into the analog input.
The 28-SSOP package has 0.65 mm pin pitch; route all analog and clock signals on the top layer with a continuous ground plane on layer 2. Place the clock driver within 25 mm of the CLK pin to limit trace-induced jitter. Use 50 ohm controlled-impedance traces for the clock and analog input; do not route digital output buses parallel to the analog input. Add a guard ring around the analog input pad connected to the analog ground plane.
Avoid driving the analog input beyond the datasheet common-mode range when using a single-ended drive - this causes severe distortion. Do not operate the converter with the digital outputs left floating; unused CMOS outputs should be tied to a defined logic level. If the analog input bandwidth must be confirmed for undersampling applications, consult the manufacturer datasheet directly because this parameter is not visible in the search snippets provided.
Separate analog and digital sections of the PCB with a clear keep-out zone around the converter. The 28-SSOP package's exposed lead frame on the bottom should be soldered to a copper pad for thermal dissipation. Place decoupling capacitors with the shortest possible loop area; vias should connect directly to the ground plane rather than through long traces. If using the part in a multi-channel system, route clock traces in a star topology from a central low-jitter buffer.
