TDA19978B

TDA19978B Quad HDMI 1.3a receiver interface with equalizer (HDTV up to 1080p, up to UXGA for PC formats) Rev. 02 — 10 May 2010 Product data sheet 1. General description The TDA19978B 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 which are laboratory tested with a 0.5 mm (24 AWG) cable at 2.05 gigasamples per second. In addition, the TDA19978B is delivered with software drivers to ease configuration and use. The TDA19978B 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, OBA (One Bit Audio), DST (Direct Stream Transfer) and HBR (High Bit Rate) stream The TDA19978B 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 OBA (as used in SACD), DST and HBR stream support The TDA19978B converts HDMI streams without HDCP into RGB or YCbCr digital sign...
