GENERAL DESCRIPTION
The AD9230-11 is an 11-bit monolithic sampling analog-to-
digital converter (ADC) optimized for high performance,
low power, and ease of use. The product operates at up to a
200 MSPS conversion rate and is optimized for outstanding
dynamic performance in wideband carrier and broadband
systems. All necessary functions, including a track-and-hold
(T/H) amplifier and voltage reference, are included on the
chip to provide a complete signal conversion solution.
The ADC requires a 1.8 V analog voltage supply and a
differential clock for full performance operation. The digital
outputs are LVDS (ANSI-644) compatible and support twos
complement, offset binary format, or Gray code. A data clock
output is available for proper output data timing.
Fabricated on an advanced CMOS process, the AD9230-11 is
available in a 56-lead lead frame chip scale package, specified
over the industrial temperature range (−40°C to +85°C).

High Performance. Maintains 62.5 dBFS SNR
@ 200 MSPS with a 70 MHz input.
Low Power. Consumes only 373 mW @ 200 MSPS.
Ease of Use. LVDS output data and output clock signal
allow interface to current FPGA technology. The on-chip
reference and sample-and-hold provide flexibility in
system design. Use of a single 1.8 V supply simplifies
system power supply design.
Serial Port Control. Standard serial port interface (SPI)
supports various product functions, such as data formatting,
disabling the clock duty cycle stabilizer, power-down, gain
adjust, and output test pattern generation.

... At input frequencies in the second Nyquist zone and above, the performance of most amplifiers may not be adequate to achieve the true performance of the AD9230-11. This is especially true in IF undersampling applications where frequencies in the 70 MHz to 100 MHz range are being sampled. For these applications, differen- tial transformer coupling is the recommended input configuration ...

... This allows a wide range of clock input duty cycles without affecting the perform- ance of the AD9230-11. When the DCS is on, noise and distortion performance are nearly flat for a wide range of duty cycles. However, some applications may require the DCS function to 0.1µ ...

... The digital power dissipation does not vary much because it is determined primarily by the DRVDD supply and bias current of the LVDS output drivers. By asserting PWDN (Pin 29) high, the AD9230-11 is placed in standby mode or full power-down mode, as determined by the contents of Register 0x08. Reasserting the PWDN pin low returns the AD9230-11 to its normal operational mode ...

... Configuration Using the SPI section. An output clock signal is provided to assist in capturing data from the AD9230-11. The DCO is used to clock the output data and is equal to the sampling clock (CLK) rate. In single data rate mode (SDR), data is clocked out of the AD9230-11 and must be captured on the rising edge of the DCO ...

... The pins described in Table 9 comprise the physical interface between the user’s programming device and the serial port of the AD9230-11. All serial pins are inputs, which is an open- drain output and should be tied to an external pull-up or pull-down resistor (suggested value of 10 kΩ). ...
