Analog Devices Inc. AD9219ABCPZ-65

Overview

AD9219ABCPZ-65 from Analog Devices is a quad-channel, 10-bit, 65 MSPS serial LVDS analog-to-digital converter operating from a single 1.8 V supply, delivering 60 dB SNR and 78 dBc SFDR at Nyquist with 315 MHz full-power analog bandwidth. It integrates four pipeline ADCs in one RoHS-compliant 48-lead LFCSP package and targets high-density signal acquisition in ultrasound beamforming and quadrature radio receivers.

For engineers reviewing the AD9219ABCPZ-65 datasheet, AD9219ABCPZ-65 pinout, AD9219ABCPZ-65 application, or AD9219ABCPZ-65 equivalent, key selection criteria include its 65 MSPS sampling rate, LVDS serial output compliance (ANSI-644), 94 mW/channel power at full speed, programmable clock/data alignment, and support for individual-channel power-down modes.

Technical Context

The AD9219ABCPZ-65 implements four independent 10-bit pipeline ADC cores sharing a common 1.8 V AVDD supply and LVDS-compatible clock interface (CLK±), each producing serialized 10-bit offset-binary data via dedicated D± differential pairs. It uses an internal 1.0 V reference and supports 2 V p-p differential analog inputs across four fully isolated input channels (VIN±A–D).

Timing is governed by a single external sample clock, which the device internally multiplies to generate DDR-aligned LVDS data clocks (DCO±) and frame clocks (FCO±); pipeline latency is fixed at 8 clock cycles, and aperture jitter is <1 ps rms. Serial port control (SPI via CSB/SCLK/SDIO) enables real-time configuration of output resolution, bit orientation, test pattern generation, and power modes.

FAQ

What is the maximum sampling rate supported by the AD9219ABCPZ-65?

The AD9219ABCPZ-65 supports a maximum sampling rate of 65 MSPS per channel, as confirmed in the Rev. G datasheet Table 4. This rate is achievable across all four integrated ADCs simultaneously under specified conditions: AVDD = DRVDD = 1.8 V, 2 V p-p differential input, and proper clock duty cycle. Operation above 65 MSPS is not characterized or guaranteed.

Does the AD9219ABCPZ-65 require an external voltage reference?

No, the AD9219ABCPZ-65 includes an internal 1.0 V reference and operates with a 2 V p-p differential analog input range without external reference components. The VREF pin can serve as input or output depending on SENSE pin configuration, but external reference use is optional and not required for standard operation.

How many differential analog input channels does the AD9219ABCPZ-65 provide?

The AD9219ABCPZ-65 provides four fully independent differential analog input channels - labeled VIN±A, VIN±B, VIN±C, and VIN±D - each with matched gain, offset, and linearity. Pin assignments are defined in the Rev. G datasheet Figure 5 and Table 7, with physical layout optimized for minimal crosstalk (<−100 dB).

What LVDS standard does the AD9219ABCPZ-65 comply with for its serial outputs?

The AD9219ABCPZ-65 serial digital outputs (D±A–D, DCO±, FCO±) comply with ANSI TIA/EIA-644 LVDS standard by default, as stated in the Features section and Table 3 of the Rev. G datasheet. A low-power reduced-swing option (150–250 mV VOD) is also supported via SPI configuration for EMI-sensitive applications.

Can the AD9219ABCPZ-65 operate with a single 1.8 V supply?

Yes, the AD9219ABCPZ-65 operates from a single 1.8 V supply for both analog (AVDD) and digital driver (DRVDD) domains, as specified in the General Description and Table 1. Both supplies must be independently decoupled, and the exposed pad must be connected to AGND to ensure thermal and electrical performance per the Rev. G datasheet recommendations.
