TVP5150AM1ZQC

Encoders, Decoders, Converters Overview

The TVP5150AM1ZQC is an ultralow-power NTSC/PAL/SECAM video decoder manufactured by Texas Instruments. It converts analog baseband video signals into digital YCbCr 4:2:2 component video or ITU-R BT.656 format. The device features a high-speed 9-bit analog-to-digital converter (ADC) and supports two composite inputs or one S-video input. It operates on a single 3.3-V supply with typical power consumption of 115 mW, dropping below 1 mW in power-down mode. The unit is housed in a 48-terminal PBGA package (ZQC) and functions within a commercial temperature range of 0°C to +70°C.

Encoders, Decoders, Converters Procurement Notes

Verify the specific ordering suffix ZQC corresponds to the 48-terminal PBGA package configuration. Confirm that the commercial temperature grade (0°C to +70°C) meets the operational requirements of the target environment. Ensure I2C interface compatibility with the host controller for register programming and control.

Encoders, Decoders, Converters Selection Notes

Select this component when a compact footprint is required due to the space-saving PBGA packaging. Choose this model over TQFP variants if board real estate is limited. Verify that the 3.3-V digital I/O supply voltage aligns with the system logic levels. Consider the industrial grade variant if operation outside the commercial temperature range is necessary.

Encoders, Decoders, Converters Part Context

This part belongs to the TVP5150AM1 series of ultralow-power video decoders. It shares functional architecture with other members like the TVP5150AM1PBS but differs in physical packaging. The ZQC suffix specifically denotes the 48-terminal PBGA form factor, distinguishing it from the 32-terminal TQFP options available in the same product family.

Encoders, Decoders, Converters FAQ

What is the maximum input voltage range for the analog video inputs?

The maximum input voltage range is 0-0.75 VPP. Signals exceeding this level may require attenuation.

How does the device handle vertical blanking interval (VBI) data?

The internal VBI data processor slices, parses, and performs error checking on teletext, closed caption, and other data formats, storing results in a FIFO or registers accessible via I2C.

Is a crystal required for operation?

Yes, the device uses a single 14.31818-MHz crystal for all supported video standards to generate the necessary sampling clocks.
