TDA9885HN/V5,118

Video Processing Overview

The TDA9885HN/V5,118 is an I2C-bus controlled single and multistandard alignment-free IF-PLL demodulator designed for negative modulation only. It operates with a 5 V supply voltage (4.5 V to 5.5 V range) and features a gain-controlled wideband Vision Intermediate Frequency (VIF) amplifier. The device includes a fully integrated VIF Voltage-Controlled Oscillator (VCO), digital acquisition help, and Automatic Frequency Control (AFC). It supports vision carrier operating frequencies of 33.4 MHz, 33.9 MHz, 38.0 MHz, 38.9 MHz, 45.75 MHz, and 58.75 MHz. The typical supply current is 63 mA.

Video Processing Procurement Notes

Verify the specific package type HVQFN32 matches the design requirements. Confirm the ordering suffix /V5 indicates the correct revision level. Ensure the negative modulation constraint aligns with the system signal standards. Check pin compatibility for the 32-terminal layout.

Video Processing Selection Notes

Select this component for systems requiring negative modulation processing only. The TDA9886 variant is required if positive modulation or SECAM support is needed. Consider the I2C-bus address configuration options available via pin resistors. Evaluate the need for external components for loop filters and de-emphasis networks.

Video Processing Part Context

This part belongs to the TDA9885/TDA9886 family of IF-PLL demodulators from NXP Semiconductors. It is specifically the TDA9885 variant, which differs from the TDA9886 by supporting negative modulation only and lacking SECAM standard support. The HN suffix denotes the HVQFN32 package.

Video Processing FAQ

Does the TDA9885HN/V5 support positive modulation?

No, the TDA9885 is designed for negative modulation only. Positive modulation requires the TDA9886.

How is the I2C-bus slave address configured?

Four selectable addresses are available, chosen by connecting resistors on pins SIOMAD, SIF1, and SIF2.
