GENERAL DESCRIPTION

The AD9980 is a complete, 8-bit, 95 MSPS, monolithic analog

interface optimized for capturing YPbPr video and RGB

graphics signals. Its 95 MSPS encode rate capability and full-

power analog bandwidth of 200 MHz supports all HDTV

video modes and graphics resolutions up to XGA (1024 × 768

at 85 Hz).

With internal Coast generation, the PLL maintains its output

frequency in the absence of sync input. A 32-step sampling

clock phase adjustment is provided. Output data, sync, and

clock phase relationships are maintained.

The auto-offset feature can be enabled to automatically restore

the signal reference levels and to automatically calibrate out any

offset differences between the three channels. The AD9980 also

offers full sync processing for composite sync and sync-on-

green applications. A clamp signal is generated internally or

may be provided by the user through the CLAMP input pin.

The AD9980 includes a 95 MHz triple ADC with an internal

reference, a phase-locked loop (PLL), programmable gain,

offset, and clamp controls. The user provides only 3.3 V and

1.8 V power supplies and an analog input. Three-state CMOS

outputs may be powered from 1.8 V to 3.3 V.

Fabricated in an advanced CMOS process, the AD9980 is

provided in a space-saving, 80-pin, Pb-free, LQFP surface

mount plastic package. It is specified over the 0°C to +70°C

temperature range.

The AD9980’s on-chip PLL generates a sample clock from

the three-level sync (for YPbPr video) or the horizontal sync

(for RGB graphics). Sample clock output frequencies range from

10 MHz to 95 MHz. PLL clock jitter is 9% or less p-p typical at

95 MSPS.
