TDA19977B Datasheet | NXP Semiconductors

description The TDA19977A; TDA19977B is a three input HDMI 1.4a pliant 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) - Improved audio clock generation using an external reference clock - OBA (as used in SACD), DST and HBR stream support The TDA19977A; TDA19977B converts HDMI streams with or without HDCP (TDA19977A only) into RGB or YCb Cr digital signals. The YCb Cr digital output signal can be 4:4:4 or 4:2:2 semi-planar format based on the ITU-R BT.601 standard or 4:2:2 based on the ITU-R BT.656 format. The device can adjust the output timing of the video port by altering the values of tsu(Q) and th(Q). In addition, all settings are controllable using the I2C-bus. .Data Sheet.in NXP Semiconductors TDA19977A; TDA19977B Triple input HDMI receiver interface with digital processing 2. Features and...
