ADV7181CBCPZ-REEL

Overview

The ADV7181CBCPZ-REEL is a multiformat SDTV video decoder and RGB graphics digitizer manufactured by Analog Devices Inc. It features four 10-bit ADCs sampling up to 110 MHz, supporting NTSC, PAL, and SECAM standards alongside component HDTV formats like 720p and 1080i. The device digitizes RGB graphics up to 1280 × 1024 at 60 Hz. It operates with a digital core supply of 1.65 V to 2.0 V, a digital I/O supply of 3.0 V to 3.6 V, an analog supply of 3.15 V to 3.45 V, and a PLL supply of 1.71 V to 1.89 V. The unit is housed in a 64-lead LQFP package.

Procurement Notes

Verify the specific ordering suffix REEL indicates tape and reel packaging upon procurement. Confirm that the ADV7181CBCPZ variant matches the required pinout and thermal specifications for the target PCB layout. Ensure the supplier provides documentation confirming the Pb-free status and RoHS compliance as specified in the manufacturer's datasheet.

Selection Notes

Select this component when a single-chip solution is required for both SDTV decoding and RGB graphics digitization. Consider the industrial temperature range of −40°C to +85°C for harsh environments. Evaluate the power consumption requirements across different operating modes, such as SCART or high-resolution graphics sampling, to ensure adequate thermal management.
