Product data sheet Rev. 02 — 10 May 2010 9 of 38 NXP Semiconductors TDA19978B Quad HDMI 1.3a receiver with digital processing [1] P = power supply; G = ground; I = input; O = output and I/O = input/output. [2] Connected to the ground of the HDMI receiver (VSSH) in normal operation. 8. Functional description The TDA19978B converts digital data streams input by the HDMI sources into parallel digital data for use by media and video signal processing integrated circuits in devices for HDTV. Data streams can be decoded without HDCP protection. Outputs from the TDA19978B can be RGB 4:4:4, YCbCr 4:4:4, YCbCr 4:2:2 semi-planar format based on the ITU-R BT.601 standard or YCbCr 4:2:2 based on the ITU-R BT.656 format. Inputs can be both progressive and interlaced formats. The TDA19978B comprises a color space conversion block, downsampling filters and an embedded timing code function. In addition, the repeater function enables other HDMI devices to be connected to form an extended “total application”. 8.1 Software drivers Software drivers are provided for easy configuration and use of the TDA19978B. These drivers can be integrated with a large range of processors, with or without an operating system. They control activity detection, input selection, video mode identification, color conversion, Power-down modes and InfoFrame notification. 8.2 HDMI inputs Control of the four HDMI inputs can be automatic using activity detection or using the I2C-bus. The HDMI receiver inputs are defined by pins RXx0+, RXx0 −, RXx1+, RXx1−, RXx2+, RXx2 −, RXxC+, RXxC−, RRX1, RRX2, HSCLx and HSDAx (x equals A, B, C or D as applicable). 8.3 Termination resistance control The HDMI receiver input contains a termination resistance control set by an external resistor connected between pins RRXx and VDDH(3V3) (x equals 1 for inputs A and B or 2 for inputs C and D). Typically, the characteristic impedance is 50 Ω and the default value of the external terminal control resistor is 12 k Ω ± 1 %.
