TDA19998HL Smart HDMI 1.4a (4 : 1) switch with auto-adaptive equalizer Rev. 3 4 August 2010 Product data sheet 1. General description The High-Definition Multimedia Interface (HDMI) switch enables connection of multiple DVI/HDMI inputs to a receiver with at least one input. The TDA19998HL is a switch with four HDMI 1.4a compliant DVI/HDMI inputs and one DVI/HDMI output. Each HDMI input has its own dedicated embedded EDID memory. A fifth DDC-bus input is available for VGA or second HDMI input of SoC. The built-in auto-adaptive equalizer improves signal quality, allowing the use of cable lengths up to 30 m. The TDA19998HL supports Deep Color mode in 10-bit and 12-bit per channel up to 1920 1080p at 50/60 Hz. The TDA19998HL supports DVI/HDMI streams with or without High-bandwidth Digital Content Protection (HDCP 1.4) and all Data Island packets. 2 The TDA19998HL settings are controllable via the I C-bus. 3 The TDA19998HL, pin compatible with TDA19997, is embedding theF technolog from NXP, allowing no delay in switching from one HDMI port to any other HDMI port while keeping HDMI output stream encrypted. 2. Features and benefits Complies with the HDMI 1.4a, DVI 1.0, EIA/CEA-861D and HDCP 1.4 standards Four independent DVI/HDMI inputs, up to 2.25 gigasamples per second Pin compatible with TDA9996/TDA9995/TDA19997/TDA19995 3 F technolog for fast switching HDMI port Robust auto-adaptive equalizer up to 20 m AWG26 at 2.25 Gbit/s up to 30 m AWG24 at 1.5 Gbit/s Integrated 50 single-ended termination resistors +5 V signal detection for each HDMI input Supports color depth processing at 24-bit, 30-bit or 36-bit per pixel Supports 3D video formats with all structures and all timings up to 2.25 GHz Supports all Data Island packets Activity detection on each input, manages output activity and power consumption Extended mode: re-generate output TMDS waveform removing jitter and skew Frequency measurement allowing direct reading of format/resolution Automatic mode for main features: Automatic Hot Plug Detect (HPD) generation and termination resistors managementTDA19998HL NXP Semiconductors Smart HDMI 1.4a (4 : 1) switch with auto-adaptive equalizer Automatic HPD generation with programmable duration Automatic EDID load Display Data Channel (DDC) bus: 5 V tolerant, DDC-bus inputs with bit rates up to 400 kbit/s One DDC-bus output with the same latency as the HDMI stream pipeline delay DDC-bus master switch functionality avoids bus corruption DDC-bus level-shifting buffer with digital lock-up protection A fifth DDC-bus input available for VGA or second HDMI input of SoC 2 I C-bus controllable at bit rates up to 400 kbit/s Non-volatile memory for switch management (Hot Plug Detect, Power-down) Embedded Extended Display Identification Data (EDID) memory: 5 embedded EDID memory supplied by +5 V from HDMI source 253-byte shared and 3-byte of dedicated EDID memory per HDMI input Non-volatile memory for programming default EDID content Supports sources without +5 V An extra 128-byte blocks for DVI or PC formats 2 EDID update by I C-bus, example for AVR applications Fail-safe output in Idle mode Mute pin preventing from pop noise/image noise ATC/Rx compliant for 36-bit Deep Color 1080p 60 Hz ATC/Tx eye diagram compliant for 36-bit Deep color 1080p 60 Hz Programmable slave address Ready for HDMI Ethernet Audio return Channel (HEAC) 3.3 V and 1.8 V power supplies Additional ESD protection pin for CEC line ESD protection: HBM: class 2 MM: class B FCDM: class IV IEC 61000-4-2 class 3 for HDMI inputs Power-down mode with dedicated pin CMOS process Lead (Pb) free LQFP100 14 14 1 mm package, pitch 0.5 mm 3.
