TDA19977AHV/15,518

Specialized Overview

The TDA19977AHV/15,518 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 at 2.25 gigasamples per second. It supports TV resolutions up to 1920 × 1080p at 50/60 Hz and PC resolutions up to UXGA (1600 × 1200p at 60 Hz). The device handles Deep Color modes in 10-bit and 12-bit formats and processes color gamut metadata packets. It converts HDMI streams into RGB or YCbCr digital signals with output formats including RGB 4:4:4, YCbCr 4:4:4, and YCbCr 4:2:2 semi-planar based on ITU-R BT.601. Audio capabilities include up to four S/PDIF or I2S-bus outputs at sampling rates up to 192 kHz and HBR audio stream support up to 768 kHz. The device operates on 1.8 V and 3.3 V power supplies and is housed in a lead-free HLQFP144 package.

Specialized Feature Summary

• Triple independent HDMI inputs with embedded auto-adaptive equalizer for signal quality improvement
• Supports Deep Color processing in 8-bit, 10-bit, and 12-bit per color depths
• Integrated HDCP decryption function with non-volatile OTP key storage for security
• Advanced audio processing including HBR stream support and system clock generation for external DACs

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 ordering suffix /15,518 against official NXP documentation to confirm tape and reel packaging details. Ensure compatibility with the HLQFP144 thermal enhanced low profile quad flat package specifications during integration. Confirm that the required software drivers are obtained from authorized NXP channels for proper configuration of the I2C-bus interface and HDCP functions.

Specialized Selection Notes

Select this component when a design requires three simultaneous HDMI inputs with automatic source switching via activity detection. It is suitable for applications needing robust HDCP 1.2 compliance with repeater capability and high-quality video conversion up to WUXGA reduced blanking. Consider its integrated audio PLL and DSD/DST support if complex audio routing without external processors is desired.

Specialized Part Context

This part belongs to the TDA19977A/B series of triple input HDMI receivers manufactured by NXP Semiconductors. It is designed as a comprehensive solution for converting digital HDMI data streams into parallel digital formats for downstream media processing. The device integrates essential functions like equalization, color space conversion, and audio formatting into a single CMOS process chip.

Specialized Replacement Considerations

The TDA19977BHV serves as a functional alternative within the same family but lacks the HDCP decoding and OTP memory features found in the TDA19977A variant. Verify if HDCP compliance is mandatory for the target application before considering the B-series replacement.

Specialized FAQ

Does the TDA19977AHV support HDCP?

Yes, the TDA19977A variant includes an HDCP decryption function with keys stored in non-volatile OTP memory, enabling it to manage all HDCP repeater functions based on the HDCP 1.2 specification.

What is the maximum supported video resolution?

The device supports TV resolutions up to 1920 × 1080p at 50/60 Hz and PC resolutions up to UXGA (1600 × 1200p at 60 Hz), including WUXGA with reduced blanking format.

How does the device handle audio clock generation?

It generates a 128/256/512 × fs system clock, allowing the use of simple audio DACs without an integrated PLL. It also supports improved audio clock generation using an external reference clock.
