SAA7118E/V1,518

Encoders, Decoders, Converters Overview

The SAA7118E/V1,518 is a video decoder manufactured by NXP Semiconductors, designed for high-quality analog-to-digital conversion of composite and component video signals. It features four-channel analog preprocessing with automatic clamp control and programmable gain, followed by four 9-bit CMOS analog-to-digital converters. The device supports multiple television standards including PAL, NTSC, and SECAM, utilizing adaptive comb filtering for luminance-chrominance separation. Key electrical parameters include a digital supply voltage (VDDD) range of 3.0 V to 3.6 V, an analog supply voltage (VDDA) range of 3.1 V to 3.5 V, and a typical total power consumption of 1.1 W. The operating temperature range extends from 0°C to 70°C.

Encoders, Decoders, Converters Procurement Notes

Verify the specific suffix /V1,518 against official documentation to confirm packaging details and compliance status. Ensure compatibility with system power requirements, specifically the 3.3 V nominal supply rails for both digital and analog domains. Confirm that the PBGA156 package dimensions align with the target PCB layout constraints.

Encoders, Decoders, Converters Selection Notes

Select this component when multi-standard video decoding with integrated analog preprocessing is required. It is suitable for applications needing direct digitization of CVBS, Y/C, or component inputs without external ADCs. Consider thermal management for the 1.35 W maximum power dissipation in enclosed environments.
