HI5767/4CBZ Обзор
An ADC (Analog-to-Digital Converter) is a mixed-signal data conversion IC that translates continuous analog input voltages into discrete digital codes. As a pipelined flash ADC, the HI5767/4CBZ uses a multi-stage architecture to achieve high sample rates while maintaining low power consumption, occupying the middle ground between full-flash converters (faster, more power) and successive-approximation ADCs (slower, less power). Within the broader component hierarchy, this device belongs to: data converter -> ADC -> pipelined ADC -> high-speed ADC -> mixed-signal IC -> semiconductor.
Key specifications include 10-bit resolution, a 40 MSPS typical sampling rate, single +5V analog supply operation, internal 2.5V bandgap voltage reference, low-power CMOS architecture, and a parallel CMOS-compatible digital output bus. The device supports both internal and external reference modes, providing flexibility for precision and drift-critical designs. It features an input bandwidth suitable for IF undersampling and video-speed applications, and the CMOS fabrication process ensures low power dissipation (typically under 200 mW) compared to bipolar flash converters of similar speed.
Typical applications include digital video processing, high-speed instrumentation, IF sampling in communications receivers, medical imaging front-ends, radar signal processing, and digital oscilloscopes. The internal reference eliminates the need for an external reference IC in cost-sensitive designs, while the parallel output bus simplifies interface to FPGAs and ASICs. The wide SOIC-28 package footprint allows hand-solderable prototyping and rework-friendly manufacturing compared to fine-pitch QFN alternatives.
When designing with the HI5767/4CBZ, ensure the analog input is driven from a low-impedance, wideband buffer (such as a high-speed op-amp) to avoid aperture jitter and maintain SNR at the rated sampling rate. Decouple AVDD and DVDD separately to prevent digital switching noise from coupling into the analog input path. Use controlled-impedance PCB layout techniques for the analog input trace to preserve bandwidth and minimize reflections at high input frequencies.

Digital Oscilloscope Front-End
The HI5767/4CBZ is well-suited to mid-bandwidth digital oscilloscope and data-acquisition front-ends where 10-bit resolution at 40 MSPS is sufficient. The pipelined architecture delivers wide analog input bandwidth so the input stage can drive signals at or near the Nyquist frequency without aliasing, while the parallel CMOS digital output interfaces directly to an FPGA or ASIC capture buffer without an external serializer. The internal 2.5 V reference eliminates one analog component in the BOM, reducing both cost and PCB area in portable or handheld oscilloscope designs. Compared with bipolar flash ADCs of similar speed, the CMOS HI5767/4CBZ typically dissipates under 200 mW, simplifying thermal management in fan-less enclosures. The 28-SOIC wide-body package remains hand-solderable for prototype builds and is rework-friendly for production.

IF Sampling in Communications Receivers
In narrowband and broadband communications receivers, the HI5767/4CBZ supports IF undersampling of intermediate-frequency signals in the 30-70 MHz range thanks to its wide analog input bandwidth. The 40 MSPS sample rate allows direct downconversion of IF carriers to baseband without a dedicated analog mixer stage, simplifying the receiver signal chain. The internal voltage reference provides stable gain calibration across temperature, critical for demodulation accuracy in cellular, land-mobile-radio, and point-to-point microwave links. The parallel 10-bit CMOS output bus feeds directly into a downstream digital downconverter (DDC) implemented in an FPGA. Pipelined CMOS architecture provides low power operation suitable for portable and battery-powered radio designs.

Заметки по проектированию
Place the HI5767/4CBZ analog input trace on the top layer with a continuous ground plane underneath to maintain controlled impedance (typically 50 ohm for 40 MSPS). Route the 10 parallel digital output traces with matched lengths to avoid data-bus skew - even 200 ps of mismatch can cause errors at 40 MSPS. Keep the AIN trace short and avoid vias in the analog input path; high-speed op-amp buffers should be placed within 5 mm of the AIN pin to minimize parasitic capacitance.
Decouple AVDD and DVDD separately with a 10 uF bulk capacitor and a 0.1 uF ceramic bypass capacitor placed within 2 mm of each supply pin. Use a ferrite bead or pi-filter between the analog and digital +5V rails to prevent digital switching noise from coupling into the analog input path. Add 10 nF bypass caps on every AVDD pin (4 pins total on the SOIC-28 footprint) to suppress high-frequency noise spikes. Estimated: the internal reference draws microamps and can share the analog supply rail, but separate filtering is recommended for precision designs.
Drive the analog input with a low-impedance, wideband op-amp buffer such as the AD8045 or LMH6702 to maintain SNR at the rated 40 MSPS sample rate. Source impedance above 50 ohm degrades aperture jitter performance and reduces effective ENOB. Use a 50-ohm series termination resistor at the CLK input to prevent reflections and avoid clock instability. Route the CLK signal on an inner layer with a continuous ground reference to minimize EMI emissions and avoid coupling into the analog input trace.
Do not exceed the absolute maximum analog input voltage of AVDD + 0.3 V; over-voltage on AIN can permanently damage the ESD protection diodes. Always operate the part with the PD (power down) pin tied low for normal operation - leaving it floating can cause unpredictable shutdown behavior. The internal 2.5V reference requires a 0.1 uF REFCAP bypass capacitor; omitting this capacitor causes reference instability and ADC code drift. Do not drive the digital outputs with external pull-ups above DVDD + 0.3 V; the CMOS output drivers are rated to 3.6 V maximum.
