Furthermore,
The output of the mixer core is taken directly from its open collectors. The open collector outputs present a high impedance at the IF frequency. The conversion gain of the mixer depends directly on the impedance presented to these open collectors. In characterization, a 100 . load was presented to the part via a 2:1 impedance transformer. The device also features a power-down function. Application of a logic low at the PWDN pin allows normal operation. A high logic level at the PWDN pin shuts d

The AD9551 Revision D evaluation board is a compact, easy to use platform for evaluating all features of the AD9551 multiservice clock generator. The AD9551 accepts one or two reference input signals to synthesize one or two output signals. The AD9551 uses a fractional-N PLL that precisely translates the reference frequency to the desired output frequency. The input receivers and output drivers provide both single-ended and differential operation. Reference conditioning and switchover circuitry
The AD9843A’s signal chain consists of an input clamp, correlated double sampler (CDS), digitally controlled variable gain amplifier (VGA), black level clamp, and 10-bit A/D converter. Additional input modes are provided for processing analog video signals. The internal registers are programmed through a 3-wire serial digital interface. Programmable features include gain adjustment, black level adjustment, input configuration, and power- down modes. The AD9843A operates from a single 3 V power s
Its 140 MSPS encode rate capability and full power analog bandwidth of 300 MHz supports resolutions up to SXGA (1280 . 1024 at 75 Hz). The AD9883A includes a 140 MHz triple ADC with internal 1.25 V reference, a PLL, and programmable gain, offset, and clamp control. The user provides only a 3.3 V power supply, analog input, and HSYNC and COAST signals. Three-state CMOS outputs may be powered from 2.5 V to 3.3 V. The AD9883A’s on-chip PLL generates a pixel clock from HSYNC and COAST inputs. Pixel
