HMCAD1102 - Octal 12-Bit 80 MSPS ADC LVDS | Analog Devices
MPN： HMCAD1102 ✓ 啟用中HMCAD1102 概覽
An ADC (Analog-to-Digital Converter) is a data converter IC that transforms continuous analog signals into discrete digital codes for processing by FPGAs, ASICs, DSPs, or microcontrollers. The HMCAD1102 belongs to the broader category hierarchy of ADC -> data converter -> signal chain IC -> mixed-signal semiconductor. Multi-channel, high-speed pipeline ADCs like the HMCAD1102 are critical in systems where multiple analog signals must be captured simultaneously - radar arrays, medical imaging front-ends, and multi-antenna communication receivers - because simultaneous sampling preserves phase relationships between channels that interleaved ADCs cannot guarantee.
Key specifications include 8 single-ended analog inputs, internal 1.2V bandgap reference, LVDS-compatible serial data outputs at up to 320 Mbps per channel, an SPI-compatible serial control interface, and a typical power dissipation of approximately 60 mW per channel at 80 MSPS. The 64-pin HQCCN SMT package (9x9 mm body) provides a compact footprint suitable for high-density PCB designs, while the operating temperature range covers -40C to +85C industrial grade.
The HMCAD1102 uses a proprietary pipelined architecture with internal sample-and-hold and multi-bit pipeline stages per channel. Each channel has an independent LVDS serializer that combines the 12 (or 14) bit samples into a single LVDS differential pair, drastically reducing the output pin count compared to parallel-output ADCs and simplifying PCB routing for multi-channel systems.
Typical applications include multi-channel digital oscilloscopes, phased-array radar and sonar receivers, medical ultrasound imaging systems, communications test equipment, and industrial multi-sensor data acquisition. The 8-channel simultaneous sampling makes the part especially suitable for any application requiring time-correlated multi-channel acquisition.
When designing with this part, allocate PCB layers carefully - serialized LVDS outputs still require controlled-impedance routing (100 ohm differential) and length matching within a channel group. Decouple each analog supply pin with 100 nF and 10 uF ceramic capacitors placed as close to the IC as possible. Avoid routing LVDS pairs near switching power supply traces to preserve SNR.

典型應用
HMCAD1102 適用於 6 應用s: Multi-Channel Digital Oscilloscope, Phased-Array Radar and Sonar Receiver, Medical Ultrasound Imaging System, Communications Test Equipment, Industrial Multi-Sensor Data Acquisition, Security and Surveillance Multi-Camera Capture.
Multi-Channel Digital Oscilloscope
The HMCAD1102 is well suited for multi-channel digital oscilloscope front-ends because it provides 8 simultaneously-sampled 12-bit channels at 80 MSPS each, preserving exact inter-channel phase relationships critical for timing and triggering analysis. Its serialized LVDS output reduces PCB trace count from 96 (parallel 12-bit) to just 16 (1 differential pair per channel), enabling compact 4-layer board designs. The internal reference eliminates an external reference IC, simplifying BOM and board area. Per the Analog Devices datasheet, typical SNR at 80 MSPS exceeds 70 dBFS, sufficient for general-purpose and mid-tier oscilloscope accuracy.
推薦
Phased-Array Radar and Sonar Receiver
The HMCAD1102 fits phased-array radar and sonar receiver channels because 8 simultaneous-sampling channels at 80 MSPS provide time-correlated digital snapshots of array elements. This preserves inter-element phase coherence required for beamforming algorithms. Per the Analog Devices HMCAD1102 datasheet, the LVDS output pairs are source-synchronous, allowing deterministic inter-channel delay calibration in the FPGA. The 64-pin HQCCN package supports the dense array layouts typical of conformal antennas. Lower sampling modes (40 MSPS, 20 MSPS) can be selected to reduce power when system requirements allow.
推薦
Medical Ultrasound Imaging System
The HMCAD1102 serves medical ultrasound imaging front-ends because ultrasound beamforming requires 8 to 128 simultaneously-sampled channels. With 8 channels per chip, beamformer boards typically use multiple HMCAD1102 devices cascaded with synchronized clocks. The 12-bit resolution and 80 MSPS rate are appropriate for ultrasound frequencies up to about 20 MHz, and the serialized LVDS output keeps the cable and interconnect count manageable between the analog front-end and the digital beamformer FPGA. The -40C to +85C industrial temperature range supports both clinical and portable/field deployment.
推薦
Communications Test Equipment
The HMCAD1102 fits communications test and measurement equipment such as vector signal analyzers, spectrum analyzer IF digitizers, and multi-antenna receiver testbeds. The 80 MSPS rate captures IF signals up to about 35 MHz with margin for anti-alias filtering, while 8 channels support concurrent multi-band or MIMO analysis. Per the Analog Devices datasheet, the SPI-compatible control interface allows in-system gain and offset calibration, important for production test equipment that demands periodic recalibration. The LVDS interface simplifies connection to high-pin-count FPGAs commonly used for digital down-conversion.
推薦
Industrial Multi-Sensor Data Acquisition
The HMCAD1102 suits industrial multi-sensor data-acquisition systems such as vibration monitoring on rotating machinery, multi-axis force/torque measurement platforms, and process-control analog front-ends. The 8 simultaneously-sampled channels allow time-aligned capture of sensors that measure dynamic phenomena on a single mechanical assembly - for example, 8 accelerometers on one motor housing. The 12-bit resolution is adequate for vibration and process-control applications. The internal reference and industrial temperature rating (-40C to +85C) make the part well-suited for factory-floor and outdoor installations.
推薦
Security and Surveillance Multi-Camera Capture
The HMCAD1102 fits multi-channel surveillance capture systems because it can digitize 8 analog camera or sensor channels simultaneously at 80 MSPS, supporting HD analog video with sufficient oversampling. The serialized LVDS output keeps the digital path manageable even with many chips per chassis. Per the Analog Devices datasheet, the SPI control allows per-channel gain adjustment to compensate for varying cable runs in surveillance installations. The industrial temperature rating enables outdoor and vehicular deployment. This part is also seen in defense imaging and remote-sensing ground stations requiring time-aligned multi-channel capture.

設計說明
Decouple each AVDD pin with both a 100 nF and a 10 uF ceramic capacitor placed as close to the pin as possible (within ~2 mm). Each DRVDD and DVDD pin requires its own 100 nF + 4.7 uF bypass pair. Use a continuous ground plane on layer 2 under the ADC, with multiple vias stitching around the HQCCN exposed pad. Avoid routing LVDS pairs near any switching DC-DC converter traces; maintain at least 4 mm spacing or use a dedicated ground guard trace.
Route each LVDS output pair as a 100-ohm differential impedance (typical microstrip or stripline) with intra-pair length matching tighter than 150 mil. Inter-pair length matching within a clock domain should be within 0.25 UI of the LVDS bit interval to avoid skew-induced capture errors at the FPGA. Source-terminate the LVDS pairs adjacent to the ADC outputs rather than at the receiver end to preserve signal integrity over longer traces. Clock the LVDS outputs into the FPGA with the matching DCO (data clock output) provided by the ADC.
Do not float the RESET pin - tie to logic high through a 10 kohm resistor for normal operation, or drive it from a microcontroller if power sequencing is needed. The TEST pin must be tied to AVSS in normal operation; floating the TEST pin can place the device into a factory test mode that disrupts outputs. Confirm the analog input common-mode voltage matches the expected input swing per the datasheet before applying real signals; AC-coupling or DC-biasing networks may be needed depending on the source impedance.
