TDA19978A

TDA19978A Quad HDMI 1.3a receiver interface with equalizer (HDTV up to 1080p, up to UXGA for PC formats) Rev. 03 — 16 April 2010 Product data sheet 1. General description The TDA19978A is a four input HDMI 1.3a compliant receiver with embedded EDID memory. The built in auto-adaptive equalizer improves signal quality and allows the use of cable lengths up to 25 m (laboratory tested with a 0.5 mm (24 AWG) cable at 2.05 gigasamples per second). The HDCP key set is stored in non-volatile One Time Programmable (OTP) memory for maximum security. In addition, the TDA19978A is delivered with software drivers to ease configuration and use. The TDA19978A supports: TV resolutions: – 480i (1440 × 480i at 60 Hz), 576i (1440 × 576i at 50 Hz) to HDTV (up to 1920 × 1080p at 50/60 Hz) – WUXGA (1920 × 1200p at 60 Hz) reduced blanking format PC resolutions: – VGA (640 × 480p at 60 Hz) to UXGA (1600 × 1200p at 60 Hz) Deep Color mode in 10-bit and 12-bit (up to 205 MHz TMDS clock) Gamut boundary description IEC 60958/IEC 61937, One Bit Audio (in SACD), DST (in compressed DSD) and HBR stream The TDA19978A includes: An enhanced PC and TV format recognition system Generation of a 128/256/512 × fs system clock allowing the use of simple audio DACs without an integrated PLL (such as the UDA1334BTS) An embedded oscillator (an external crystal can also be used) Improved audio clock generation using an external reference clock One Bit Audio (in SACD), DST (in compressed DSD) and...
