Functional description
The TDA19977A; TDA19977B converts digital data streams input by the HDMI sources
into parallel digital data for use by media and video signal processing integrated circuits
such as NXP Semiconductors’ Nexperia devices for HDTV. Data streams can be decoded
with or without HDCP (TDA19977A only) protection.
Outputs from the TDA19977A; TDA19977B 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
TDA19977A; TDA19977B comprises a color space conversion block, downsampling lters
and an embedded timing code function. In addition, the HDCP (TDA19977A only)
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 conguration and use of the TDA19977A;
TDA19977B. 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
identication, color conversion, Power-down modes, HDCP (TDA19977A only) and
InfoFrame notication.
8.2 HDMI inputs
Control of the three HDMI inputs can be automatic using activity detection or using the
I2C-bus. The HDMI receiver inputs are dened by pins RXx0+, RXx0
, RXx1+, RXx1,
RXx2+, RXx2
, RXxC+, RXxC, RRXx, HSCLx and HSDAx. In the pin names, x equals A,
B or C (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). In RRXx, x equals 1 for inputs A
and B or 2 for inputs C and D. Typically, the characteristic impedance is 50
and the
default value of the external terminal control resistor is 12 k
± 1 %.
