HI5767/6CAZ Übersicht
An analog-to-digital converter (ADC) is a data-acquisition mixed-signal IC that samples a continuous analog waveform and produces a discrete digital code for downstream digital signal processing. The 10-bit pipelined flash architecture used in the HI5767 family sits hierarchically between SAR converters (slower, lower power) and full-flash converters (faster, higher power), balancing speed and die area. ADCs of this class belong to the broader family of data-converter ICs within signal-chain semiconductors, used wherever analog sensors interface with digital processors, FPGAs, or microcontrollers.
Key features of the HI5767/6CAZ include 60 MSPS maximum sampling rate, 10-bit resolution, internal voltage reference eliminating external reference components, single +5 V analog supply operation, and TTL/CMOS-compatible digital outputs. The pipelined architecture provides low-latency conversion suitable for real-time signal processing, while the integrated sample-and-hold front end minimizes aperture uncertainty and supports full Nyquist-bandwidth analog input frequencies.
From an architecture standpoint, the pipelined flash topology breaks the conversion into cascaded low-resolution stages, each stage resolving a subset of bits while driving a residue into the next stage. This approach achieves higher sampling rates than successive-approximation (SAR) converters at the cost of pipeline latency (typically 2-3 clock cycles). The internal voltage reference reduces external component count and improves power-supply noise rejection on the reference node.
Typical applications include digital video processing, high-speed data acquisition systems, CCD imaging digitizers, communications IF baseband sampling, and professional video broadcast equipment. The /6 speed grade (60 MSPS) targets standard-definition digital video (BT.601 at 27 MHz oversampled) and intermediate-frequency sampling in digital receivers.
When designing with this device, ensure the analog input drive network has 50 ohm source impedance to match the track-and-hold, decouple AVDD and DVDD with separate 0.1 uF + 10 uF capacitors placed within 5 mm of the supply pins, and respect the tRPD and tOD timing relationships between encode clock and output data. The internal reference output requires a 0.1 uF + 10 uF bypass network on the REFOUT pin.

Standard-Definition Digital Video Digitizing
The HI5767/6CAZ digitizes composite or component SD video at the BT.601 pixel rate of 27 MHz with 2x oversampling, providing 10-bit resolution (60 dB SNR) for studio-grade video capture. Its 60 MSPS sampling rate exceeds the 54 MHz Nyquist requirement for 27 MHz pixel-rate digitization, and the integrated sample-and-hold front end preserves aperture integrity at full-bandwidth luminance transients. The internal 2.5 V reference eliminates an external reference IC, reducing the video-ADC front-end BOM by 30 percent. The 28-pin SSOP package allows placement close to the video decoder FPGA with short analog input traces for minimal capacitance loading and maximum channel-to-channel skew performance. Use the /6 grade when processing 30 MHz component video and the /4 grade when only 13.5 MHz SD-SDI is required.

Designhinweise
The HI5767/6CAZ requires separate analog (AVDD) and digital (DVDD) +5 V supply rails. Place a 0.1 uF X7R ceramic bypass capacitor within 5 mm of each AVDD pin and a 10 uF tantalum or ceramic bulk capacitor on each rail within 25 mm. Ferrite-bead isolation between AVDD and DVDD prevents digital switching noise from coupling into the analog section. Add a 0.1 uF + 10 uF bypass network on REFOUT and REFBN pins to filter the internal voltage reference; insufficient bypassing degrades SNR by 3-5 dB. Estimated: assuming 1 oz copper pour on a 4-layer FR4 board, AVDD and DVDD traces should be at least 0.5 mm wide.
Route analog (VIN) and digital outputs (D0-D9) on separate PCB layers with the ground plane between them as a return-current shield. Use a 4-layer stackup (top signal, inner-1 ground, inner-2 power, bottom signal) for best signal-integrity. Keep the CLK trace under 25 mm with 50 ohm controlled impedance; terminate with a 50 ohm series resistor at the driver output to absorb reflections. Route D0-D9 as a parallel bus with matched lengths (skew under 200 ps) to avoid sample-time mismatch. Place the HI5767/6CAZ within 25 mm of the analog input source to minimize capacitance loading.
Do not share AGND and DGND as a single ground pour - route them as separate nets that tie together only at the ADC's AGND/DGND pins. Operating above 60 MSPS clock rate without proper encode-clock termination causes aperture jitter that degrades SNR by 10+ dB. Driving VIN with a source impedance greater than 100 ohms causes distortion at full-scale; use a wideband op-amp buffer with 10-50 ohm output impedance. The OE pin must be tied to logic high for normal operation; leaving it floating causes intermittent output glitches. Operating below the minimum clock rate (typically 1 MSPS) is not specified and may cause the internal bias network to malfunction.
Use a single continuous ground plane on inner-1 directly beneath the HI5767/6CAZ, and avoid routing digital traces across this plane near the analog input pin. The exposed pad (if present on the SSOP variant) should be soldered to a copper pour connected to AGND for thermal dissipation; without this connection, junction temperature rises approximately 15C per watt. Keep all high-speed digital traces (CLK, D0-D9) at least 3 mm away from the VIN trace and REFOUT pin to minimize capacitive coupling. Add ground-guard traces around the VIN input path to isolate it from digital switching noise.
