Product details
Overview
AD9653BCPZ-125 from Analog Devices is a quad-channel, 16-bit, 125 MSPS analog-to-digital converter with serial LVDS output, 1.8 V supply operation, and on-chip sample-and-hold. It delivers 76.5 dBFS SNR at 70 MHz (2.0 V p-p input) and supports medical ultrasound, quadrature radio receivers, and high-speed imaging systems requiring precise multichannel digitization.
For engineers reviewing the AD9653BCPZ-125 datasheet, AD9653BCPZ-125 pinout, AD9653BCPZ-125 application, or AD9653BCPZ-125 equivalent, key selection criteria include its 650 MHz full-power analog bandwidth, ±0.7 LSB DNL, programmable LVDS output alignment, multichip sync capability, and industrial −40°C to +85°C temperature rating.
Technical Context
The AD9653BCPZ-125 implements four independent pipeline ADC cores sharing a common clock management block and serial LVDS serializer per channel. Each core features a 16-bit resolution, 125 MSPS maximum conversion rate, and supports both ANSI-644 and reduced-range LVDS output modes.
It integrates a programmable internal voltage reference (1.0 V or 1.3 V), flexible digital test pattern generation (built-in and custom via SPI), and full chip or per-channel power-down modes consuming ≤2 mW in shutdown-enabling dynamic power scaling for multi-stage signal chains.

FAQ
What is the maximum analog input frequency supported by the AD9653BCPZ-125?
The AD9653BCPZ-125 has a full-power analog bandwidth of 650 MHz, meaning it can accurately digitize signals up to that frequency without significant amplitude roll-off. However, due to Nyquist constraints at 125 MSPS, the maximum usable input frequency before aliasing is 62.5 MHz-though undersampling applications may exploit the 650 MHz bandwidth for RF sampling above the first Nyquist zone. The AD9653BCPZ-125 maintains specified SNR and SFDR performance within this band.
Does the AD9653BCPZ-125 require an external voltage reference?
No, the AD9653BCPZ-125 includes an integrated, programmable voltage reference with two factory-trimmed settings: 1.0 V (for 2.0 V p-p input span) and 1.3 V (for 2.6 V p-p input span). External reference is optional and only needed if tighter initial accuracy or temperature drift specifications than the internal reference provides are required. The AD9653BCPZ-125 operates fully functional with the internal reference enabled.
How does the AD9653BCPZ-125 handle multichip synchronization?
The AD9653BCPZ-125 supports deterministic multichip sync via its dedicated SYNC input pin and internal pipeline latency control. When SYNC is asserted synchronously across multiple AD9653BCPZ-125 devices, their internal sampling phases align within one clock cycle, ensuring coherent sampling across channels. This capability is essential for beamforming, MIMO, and time-of-flight measurements where inter-device skew must be minimized-no external delay calibration is required.
What LVDS output modes does the AD9653BCPZ-125 support?
The AD9653BCPZ-125 supports two LVDS output configurations: standard ANSI-644 mode (±290–±400 mV differential swing) and a low-power, reduced-swing option (±160–±230 mV) compliant with IEEE 1596.3. Both modes use DDR serialization across two lanes per channel, with programmable data alignment and bit orientation via SPI. The reduced-swing mode lowers driver power by ~25% while maintaining signal integrity on controlled-impedance PCBs.
What is the pipeline latency of the AD9653BCPZ-125 and why does it matter?
The AD9653BCPZ-125 has a fixed pipeline latency of 16 clock cycles, which is deterministic and unaffected by configuration changes. This value is critical for real-time control loops and digital downconversion, where predictable delay between analog input and digital output enables accurate timing compensation in FPGA or DSP firmware. The latency is identical across all four channels, preserving phase coherence in multichannel processing-verified in the AD9653BCPZ-125 datasheet Rev. F, Table 6.
