TDA19977A

TDA19977A; TDA19977B Triple input HDMI 1.4a compliant receiver interface with equalizer (up to 1080p for HDTV, and UXGA for PC formats Rev. 3 — 19 November 2010 Product data sheet 1. General description The TDA19977A; TDA19977B is a three input HDMI 1.4a compliant receiver with embedded EDID memory. The built-in auto-adaptive equalizer, improves signal quality and allows the use of cable lengths of up to 25 m which are laboratory tested with a 0.5 mm (24 AWG) cable at 2.05 gigasamples per second. The HDCP (TDA19977A only) key set is stored in non-volatile OTP (One Time Programmable) memory for maximum security. In addition, the TDA19977A; TDA19977B is delivered with software drivers to ease configuration and use. The TDA19977A; TDA19977B 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 TDA19977A; TDA19977B 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)...
