ADS5102IPFBG4 - 10-Bit 65MSPS ADC, 1.8V, 48-TQFP | Texas Instruments
MPN： ADS5102IPFBG4 ✓ 啟用中ADS5102IPFBG4 概覽
A pipelined ADC is a type of data converter that processes the input in multiple low-resolution stages, each stage producing a partial conversion that is combined through digital error correction; pipelined ADCs dominate the 10-200 MSPS market because they balance high sampling speed with low power consumption. Within the data acquisition hierarchy, the ADS5102 sits at the intersection of the ADC (analog-to-digital converter) family, the data converter category, and the broader signal chain IC group that includes amplifiers and analog front ends.
Key differentiating specifications include: 65 MSPS maximum sample rate (with a 40 MSPS sibling, the ADS5103, sharing the same die), differential analog input supporting 1 Vp-p full-scale, internal 1.0 V reference with external override, integrated sample-and-hold, and selectable 1.8 V or 3.3 V CMOS output logic levels. The pipelined core provides 10-bit resolution with no missing codes and low differential nonlinearity (DNL) suitable for video and instrumentation front ends.
The device integrates a high-bandwidth track-and-hold amplifier front-end that minimizes aperture jitter and supports AC-coupled or DC-coupled single-ended-to-differential drive when paired with an external driver. Power consumption scales with sample rate and can be further reduced via the dedicated power-down pin, dropping quiescent current to microampere levels for battery-powered or portable instrumentation.
Typical applications include digital video recording, flat-panel display and projector processing, set-top box video capture, IF (intermediate frequency) digitization in communications receivers, portable and battery-operated test instrumentation, and CCD imaging array digitizers. Designers select the ADS5102 when they need a compact, low-power, single-supply 10-bit ADC with sufficient speed to capture baseband or downsampled IF signals.
When designing with this device, allocate adequate PCB ground plane area beneath the package and keep analog input traces length-matched and guarded by ground to preserve differential balance. Decouple AVD and DVD with separate 0.1 uF and 10 uF ceramic capacitors placed within 5 mm of each supply pin, and consider an input common-mode bias network because the ADS5102 expects a DC bias near mid-supply when driven single-ended.

典型應用
ADS5102IPFBG4 適用於 6 應用s: Digital Video Recording, Set-Top Box Video Capture, IF Signal Digitization in Communications, Portable Test Instrumentation, CCD Imaging Array Digitization, Flat-Panel Display and Projector Processing.
Digital Video Recording
The ADS5102IPFBG4 fits digital video recording front-ends because its 10-bit resolution and 65 MSPS sampling rate comfortably capture standard-definition and downsampled high-definition video streams while consuming roughly 90 mW from a single 1.8 V supply. Placed immediately after the analog video decoder and anti-alias LPF, the ADC digitizes composite or component video at 27 MHz for SD or up to 65 MHz for bandwidth-limited HD capture, providing 10-bit pixel depth for downstream MPEG/H.264 compression. Unlike 8-bit converters, the 10-bit path preserves headroom for video gain and chroma adjustments in software without quantization banding artifacts.
推薦
Set-Top Box Video Capture
The ADS5102IPFBG4 suits set-top box (STB) video capture because its differential input rejects common-mode noise from the tuner chassis while the 65 MSPS rate oversamples baseband composite video by 2-3x to relax anti-alias filter design. Powered from a 1.8 V rail shared with the demodulator, the ADC outputs 3.3 V CMOS data directly into the video processor's parallel bus, eliminating a level-shifter stage. The integrated power-down pin enables the STB to drop the ADC into standby when the user is not watching video, extending energy-star compliance.
推薦
IF Signal Digitization in Communications
The ADS5102IPFBG4 digitizes intermediate-frequency (IF) signals in communications receivers because its 65 MSPS sampling rate satisfies Nyquist for IFs up to approximately 30 MHz, and its pipelined architecture provides low aperture jitter necessary for accurate demodulation of QAM/QPSK constellations. Positioned after the mixer and SAW filter, the ADC captures the 21.4 MHz or 36.15 MHz IF directly into a digital down-converter running on the host DSP or FPGA. The differential input simplifies interface to active IF amps with 50 ohm termination.
推薦
Portable Test Instrumentation
The ADS5102IPFBG4 is a strong fit for handheld oscilloscopes, data loggers, and portable spectrum analyzers because its 1.8 V supply and integrated power-down mode yield low total power consumption, while 65 MSPS / 10-bit resolution is sufficient for capturing signals up to 25 MHz in field service tools. With the PD pin tied to a microcontroller GPIO, the ADC can sleep between acquisitions, extending battery life across an 8-hour service shift. Its small 48-TQFP 7x7 mm footprint simplifies integration into compact handheld enclosures.
推薦
CCD Imaging Array Digitization
The ADS5102IPFBG4 works well in CCD (charge-coupled device) imaging array digitizers because its differential input accepts the correlated-double-sampling (CDS) outputs commonly produced by CCD analog front-ends, and its 65 MSPS rate can digitize multi-megapixel CCD arrays at standard video frame rates. The internal 1.0 V reference simplifies the bill of materials by eliminating an external reference IC for many CDS topologies, reducing total PCB area in compact camera modules.
推薦
Flat-Panel Display and Projector Processing
The ADS5102IPFBG4 supports flat-panel display controllers and projection systems where it captures analog VGA or component video inputs at resolutions up to SXGA (1280x1024 at 60 Hz requires roughly 65 MHz pixel clock). Its 1.8 V core supply integrates easily with modern display SoCs while the selectable 3.3 V output drivers interface directly to legacy scaler ASICs. Designers appreciate the pin-compatible ADS5103 (40 MSPS) for cost-down SKUs targeted at XGA-only projectors.

主要差異化特點
- Differential input with integrated 1.0 V reference (對比ADS5103IPFB)
- Selectable 1.8 V / 3.3 V output drivers (對比ADS5102IPFB)
- Higher sample rate for full-bandwidth video capture (對比ADS5103IPFB)
設計說明
Place 0.1 uF and 10 uF ceramic decoupling capacitors within 5 mm of every AVD and DVD pin. Use a continuous analog ground plane beneath the device and route digital outputs away from the INP/INN traces to minimize digital-to-analog feedback. The 48-TQFP thermal pad is not present; copper pour helps dissipate ~90 mW but is not critical at this power level.
Drive the differential analog inputs with length-matched traces (mismatch <0.5 mm) and 50 ohm characteristic impedance terminated at the ADC pins. The CLKB pin should be AC-grounded with a 0.1 uF cap if unused; leaving it floating can inject noise into the sample-and-hold. Use the VCM pin (1/2 AVD) to bias op-amp drivers for single-ended-to-differential conversion with maximum linearity.
The DRVDD pin can be tied to either 1.8 V (matched to DVD) or 3.3 V to interface legacy 3.3 V logic. When DRVDD = 3.3 V, total power rises by ~20 mW due to higher output driver swing. Use the PD pin to drop quiescent current to microampere levels between acquisitions in battery-powered designs; de-assertion requires settling time of approximately 100 sample periods.
