AD9259 THEORY OPERATION
AD9259 architecture consists pipelined divided into three sections: 4-bit first stage followed eight 1.5-bit stages final 3-bit flash. Each stage provides sufficient overlap correct flash errors preceding stage. quantized outputs from each stage combined into final 14-bit result digital correction logic. pipelined architecture permits first stage operate with input sample while remaining stages operate with preceding samples. Sampling occurs rising edge clock. Each stage pipeline, excluding last, consists resolution flash connected switched-capacitor interstage residue amplifier (for example, multiplying digital-to-analog converter (MDAC)). residue amplifier magnifies difference between reconstructed output flash input next stage pipeline. redundancy used each stage facilitate digital correction flash errors. last stage simply consists flash ADC. output staging block aligns data, corrects errors, passes data output buffers. data then serialized aligned frame data clocks. inductors ferrite beads required when driving converter front high frequencies. Either shunt capacitor single-ended capacitors placed inputs provide matching passive network. This ultimately creates low-pass filter input limit unwanted broadband noise.

These pins biased internally require additional biasing. Figure shows preferred method clocking AD9259. jitter clock source converted from single-ended signal differential signal using transformer. back-toback Schottky diodes across secondary transformer limit clock excursions into AD9259 approximately differential. This helps prevent large voltage swings clock from feeding through other portions AD9259, preserves fast rise fall times signal, which critical jitter performance.

Clock Duty Cycle Considerations
Typical high speed ADCs both clock edges generate variety internal timing signals. result, these ADCs sensitive clock duty cycle. Commonly, tolerance required clock duty cycle maintain dynamic performance characteristics. AD9259 contains duty cycle stabilizer (DCS) that retimes nonsampling edge, providing internal clock signal with nominal duty cycle. This allows wide range clock input duty cycles without affecting performance AD9259. When noise distortion performance nearly flat wide range duty cycles. However, some applications require function off. keep mind that dynamic range performance affected when operated this mode. Memory section more details using this feature. Jitter rising edge input important concern, reduced internal stabilization circuit. duty cycle control loop does function clock rates less than nominal. loop time constant associated with that must considered applications where clock rate change dynamically. This requires wait time after dynamic clock frequency increase decrease) before loop relocked input signal. During period that loop locked, loop bypassed internal device timing dependent duty cycle input clock signal. such applications, appropriate disable duty cycle stabilizer. other applications, enabling circuit recommended maximize performance.
Another option ac-couple differential PECL signal sample clock input pins shown Figure AD9510/ family clock drivers offers excellent jitter performance.

AD9259 returns normal operating mode when PDWN pulled low. This both tolerant. power-down mode, power dissipation achieved shutting down reference, reference buffer, PLL, biasing networks. decoupling capacitors REFT REFB discharged when entering power-down mode must recharged when returning normal operation. result, wake-up time related time spent power-down mode: shorter cycles result proportionally shorter wake-up times. With recommended decoupling capacitors REFT REFB, approximately required fully discharge reference buffer decoupling capacitors approximately required restore full operation. There several other power-down options available when using SPI. user individually power down each channel entire device into standby mode. latter option allows user keep internal powered when fast wake-up times (~600 required.

AD9259 SERIAL PORT INTERFACE (SPI)
AD9259 serial port interface allows user configure converter specific functions operations through structured register space provided ADC. This provide user with additional flexibility customization, depending application. Addresses accessed serial port written read from port. Memory organized into bytes that further divided into fields, documented Memory section. Detailed operational information found AN-877 Application Note, Interfacing High Speed ADCs SPI. There three pins that define SPI: SCLK, SDIO, (see Table 14). SCLK used synchronize read write data presented ADC. SDIO dualpurpose that allows data sent read from internal memory registers. active control that enables disables read write cycles. Table Serial Port Pins

Serial Data Input/Output. dual-purpose pin. typical role this input output, depending instruction sent relative position timing frame. Chip Select (Active Low). This control gates read write cycles.
addition operation modes, port configuration influences AD9259 operates. applications that require control port, line tied held high. This places remainder pins into their secondary modes, defined SDIO/ODM SCLK/DTP sections. also tied enable 2-wire mode. When tied low, SCLK SDIO only pins required communication. Although device synchronized during power-up, user should ensure that serial port remains synchronized with line when using this mode. When operating 2-wire mode, recommended 3-byte transfer exclusively. Without active line, streaming mode entered exited. addition word length, instruction phase determines serial frame read write operation, allowing serial port used both program chip read contents on-chip memory. instruction readback operation, performing readback causes SDIO change from input output appropriate point serial frame. Data sent MSB- LSB-first mode. MSB-first mode default power-up changed adjusting configuration register. more information about this other features, AN-877 Application Note, Interfacing High Speed ADCs SPI.

SDIO bidirectional, functioning input during write phases output during readback. multiple SDIO pins share common connection, care should taken ensure that proper levels met. Assuming same load each AD9259, Figure shows number SDIO pins that connected together resulting level. This interface flexible enough controlled either serial PROMS mirocontrollers, providing user with alternative method, other than full controller, program (see AN-812 Application Note).

When brought low, device processes SCLK SDIO obtain instructions. Normally, remains until communication cycle complete. However, connected slow device, brought high between bytes, allowing older microcontrollers enough time transfer data into shift registers. stalled when transferring one, two, three bytes data. When device enters streaming mode continues process data, either reading writing, until taken high communication cycle. This allows complete memory transfers without requiring additional instructions. Regardless mode, taken high middle byte transfer, state machine reset device waits instruction.

These should located close point entry board level close parts, with minimal trace lengths. single board ground plane should sufficient when using AD9259. With proper decoupling smart partitioning board's analog, digital, clock sections, optimum performance easily achieved.
