TDA19977AHV/15,551

Specialized Overview

The TDA19977AHV/15,551 is a triple input HDMI 1.3a compliant receiver with embedded EDID memory and an auto-adaptive equalizer supporting cable lengths up to 25 m. It processes resolutions from VGA (640 × 480p) to WUXGA (1920 × 1200p) and HDTV up to 1920 × 1080p at 50/60 Hz, including Deep Color modes of 10-bit and 12-bit. The device converts HDMI streams into RGB or YCbCr digital signals with selectable color depths of 8-bit, 10-bit, or 12-bit per color. It supports audio formats including S/PDIF, I2S-bus, DSD, DST, and HBR streams up to 768 kHz. The component operates on 1.8 V and 3.3 V supplies within the HLQFP144 package.

Specialized Feature Summary

• Triple independent HDMI inputs with embedded auto-adaptive equalizer for signal quality optimization
• Supports HDCP 1.2 decryption with non-volatile OTP key storage in the TDA19977A variant
• Generates system clocks (128/256/512 × fs) enabling simple audio DAC integration without PLLs
• Includes programmable color space conversion and downsampling filters for flexible video output formatting

Specialized Applications

• High-end television sets
• Home theater amplifiers and AVRs
• Projectors and LCD/Plasma TVs
• DVD recorders and HDMI splitters

Specialized Procurement Notes

Verify the specific suffix against the manufacturer's current production status, as components may transition through lifecycle stages. Confirm that the HLQFP144 package dimensions and exposed die pad thermal requirements match the target PCB layout. Ensure the selected variant aligns with HDCP requirements, noting that only the 'A' suffix includes HDCP decoding capabilities.

Specialized Selection Notes

Select the TDA19977A variant if HDCP 1.2 decryption and repeater functionality are required for protected content playback. Choose the TDA19977B variant for applications where HDCP handling is managed externally or not needed. Consider the embedded oscillator capability versus external crystal requirements based on board space constraints. Verify that the 1.8 V and 3.3 V power supply rails are compatible with the host system design.
