AD9984AKCPZ-170

The AD9984AKCPZ-170 is a complete 10-bit, 170 MSPS monolithic analog interface from Analog Devices, optimized for capturing YPbPr video and RGB graphics signals. It incorporates a triple 10-bit ADC with an internal reference, a PLL, and programmable gain, offset, and clamp control. The full-power analog bandwidth of 300 MHz supports all HDTV video modes up to 1080p and graphics resolutions up to UXGA (1600 × 1200 at 60 Hz).

The device operates from a 1.8 V core supply (1.755 V to 1.9 V range) and features three-state CMOS outputs powered from 1.8 V to 3.3 V. A 2:1 input multiplexer on each channel allows selection between two analog inputs. The on-chip PLL generates a sample clock from tri-level sync (YPbPr) or horizontal sync (RGB), with output frequencies from 10 MHz to 170 MHz and 32-step phase adjustment. Digital output formats include 4:4:4, 4:2:2, and DDR.

The AD9984AKCPZ-170 is housed in a 64-lead LFCSP (9x9 mm, 0.95 mm height) with exposed pad for thermal management. It is surface-mountable and operates over the commercial temperature range of 0°C to 70°C. Control is via an I2C serial interface. Typical applications include advanced TVs, plasma display panels, LCD monitors, projectors, and RGB graphics processing.
