CDK8307DILP64 Overview
An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts real-world analog signals (voltage, current, sensor outputs) into discrete digital codes for processing by microcontrollers, FPGAs, or DSPs. Multi-channel ADCs like the CDK8307 integrate several ADC cores in one package, sharing clocking and reference circuits, and are widely used in medical imaging, communications infrastructure, and industrial test equipment. In the broader component taxonomy, the CDK8307 sits as: ADC -> data converter -> mixed-signal IC -> semiconductor device.
Key specifications include 12/13-bit resolution, 65 MSPS maximum sample rate, eight simultaneous sampling channels, low power consumption (around 45 mW per channel at 65 MSPS), and LVDS (Low-Voltage Differential Signaling) serial outputs that minimize digital EMI on the PCB. The proprietary internal architecture provides high spurious-free dynamic range (SFDR) and signal-to-noise ratio (SNR) suitable for demanding IF-sampling applications.
The CDK8307 uses a proprietary pipelined core with internal reference circuitry and a serial control interface (SPI-compatible) for mode programming. Its LVDS outputs allow the ADC to be placed close to the analog source while routing digital data long distances over differential pairs, reducing ground bounce and digital coupling into analog sections.
Typical applications include medical ultrasound imaging, multi-channel communications receivers, portable and battery-powered instrumentation, industrial data acquisition systems, and multi-antenna software-defined radio (SDR) platforms. The combination of eight channels, low power, and LVDS outputs makes it a strong fit for systems requiring many synchronized sample streams at low total power.
When designing with this device, route LVDS pairs as 100-ohm differential transmission lines with length matching within 5 ps, and keep the analog and digital supply domains well decoupled near the package. Provide a low-jitter clock to the CLK input - jitter directly degrades SNR at high input frequencies, so budget no more than 1 ps RMS at the ADC clock pin.

Typical Applications
CDK8307DILP64 is suitable for 6 applications: Medical Ultrasound Imaging, Multi-Channel Communications Receivers, Portable Battery-Powered Instrumentation, Industrial Multi-Sensor Data Acquisition, Phased-Array Radar and Software-Defined Radio, Multi-Antenna MIMO Baseband Digitizer.
Medical Ultrasound Imaging
The CDK8307DILP64 is well suited to portable and mid-range ultrasound systems where 8 to 64 synchronized receive channels must be digitized at low power. Its 12/13-bit resolution and 65 MSPS sample rate are appropriate for the 1-15 MHz bandwidth of diagnostic ultrasound transducers, and the LVDS outputs let the ADC sit close to the probe head while routing data to a back-end FPGA over thin differential pairs. Estimated per-channel power of about 5-6 mW helps keep the probe cable cool. Designers should match LVDS pair lengths within 5 ps and decouple AVDD and OVDD separately to preserve SNR.
Recommended
Multi-Channel Communications Receivers
The eight simultaneous-sampling channels of the CDK8307DILP64 make it a strong fit for diversity receivers and multi-antenna baseband digitizers in 4G/5G small cells. The 65 MSPS rate comfortably covers 20 MHz LTE signal bandwidths when paired with an appropriate digital down-converter, and the LVDS interface reduces EMI in dense radio boards. Sharing a single clock across all eight channels preserves phase coherence required for beamforming and MIMO signal processing. The wide 1.7-3.6 V OVDD range also lets the ADC connect directly to common FPGA banks without level translators.
Recommended
Portable Battery-Powered Instrumentation
With around 45 mW total power consumption quoted by Mouser and 1.8 V analog supply, the CDK8307DILP64 enables handheld oscilloscope probes, field data loggers, and portable spectrum analyzers that need many channels on a tight power budget. Eight channels in one 64-QFN replace what would otherwise require four or five dual-channel ADCs, reducing both PCB area and quiescent current. Designers should budget at least 10 uF of bulk decoupling on AVDD and use a low-dropout regulator with better than 30 uVrms noise to preserve SNR at the lower end of the dynamic range.
Recommended
Industrial Multi-Sensor Data Acquisition
Industrial condition-monitoring and vibration-analysis systems often need eight or more IEPE or strain-gauge channels sampled synchronously. The CDK8307DILP64's eight simultaneous channels with shared clock deliver exactly this capability, and the LVDS outputs survive the longer cable runs typical of factory-floor backplanes. The 12/13-bit resolution is sufficient for sub-kHz vibration spectra after FFT processing, while the 65 MSPS rate allows oversampling to relax analog anti-alias filter requirements. Designers should isolate the ADC grounds from motor-drive switching noise with a partitioned ground plane.
Recommended
Phased-Array Radar and Software-Defined Radio
Software-defined radio platforms and phased-array radar front-ends require phase-coherent multi-channel digitization, and the CDK8307DILP64's eight synchronized channels at 65 MSPS make it a good fit for sub-6 GHz IF sampling. The LVDS outputs are particularly attractive here because they let the digital section be physically separated from the analog RF section by a screen, reducing local-oscillator leakage. The 12/13-bit dynamic range is sufficient for many commercial radar and SIGINT applications. AAN-18 from MaxLinear documents buffer-amp interface trade-offs versus the TI ADS528x family for this use case.
Recommended
Multi-Antenna MIMO Baseband Digitizer
In 4x2 or 8x1 MIMO radio architectures, the CDK8307DILP64 can digitize all baseband I/Q streams from a multi-antenna front-end in a single 64-QFN, dramatically reducing board area versus a discrete-ADC approach. The 65 MSPS rate supports oversampling of 20 MHz LTE signals, easing analog filter design, and the 1.8 V analog supply is friendly to modern RF front-ends. Sharing one clock and reference across all eight channels preserves the I/Q phase balance essential for MIMO channel estimation. Expect an 8x1 MIMO design to drop from 4-5 dual-channel ADCs to just one CDK8307 part.

Key Differentiators
- Eight simultaneously-sampling channels in a single 64-QFN (vs CDK8307AILP64)
- Serial LVDS outputs minimize PCB routing congestion (vs CDK8307BILP64)
- 1.7-3.6 V digital supply supports direct FPGA connection (vs ADCs with fixed 1.8 V OVDD only)
Design Notes
Route all LVDS data pairs as 100-ohm differential transmission lines with intra-pair length matching within 150 mil (about 25 ps) and inter-pair matching within 5 ps to preserve channel-to-channel timing alignment. Keep the analog input traces short and guarded by ground on both sides; the eight analog inputs are high-impedance and susceptible to coupled noise. The 64-QFN exposed pad must be soldered to a continuous ground plane with at least 9 thermal vias for heat dissipation, and AVDD/OVDD should each have their own 10 uF bulk + 0.1 uF ceramic decoupling network within 5 mm of the supply pins.
The clock source is the most critical signal for SNR performance at high analog input frequencies. According to the MaxLinear CDK8307 application note AAN-18, total jitter at the CLK pin must be below about 1 ps RMS to avoid degrading SNR at 30 MHz input. Use a low-jitter clock generator such as the LMK04828 or CDCE62005 and place it within 25 mm of the ADC. Add a series ferrite bead on the clock supply and a 50-ohm source-termination resistor if the trace length exceeds 10 mm. Never use a GPIO pin to drive CLK - jitter will dominate noise performance.
Estimated: at AVDD = 1.8 V, OVDD = 3.3 V, and 65 MSPS with LVDS outputs, the CDK8307DILP64 draws approximately 45 mW total according to the Mouser listing snippet, but per-channel breakdown requires the datasheet electrical table. Design the LDO for AVDD with at least 50 mA headroom and noise below 30 uVrms; the TPS7A4700 or LT3042 are good candidates. Place input bulk capacitors on each AVDD pin and provide a pi-filter (ferrite + capacitor) on the digital OVDD supply to prevent LVDS switching noise from coupling back into the analog domain.
