1
The minimum/maximum specifications are guaranteed over the 40°C to +85°C temperature range (TMIN to TMAX).
2
All ADC linearity tests were performed at input range full scale 12.5% and at zero scale + 12.5%.
3
Pin 1, Pin 105, Pin 106, and Pin 144 are 5 V tolerant.
4
Guaranteed by characterization.
5
The VOH and VOL levels were obtained using the default drive strength value (0x15) in User Map Register 0xF4.
6
Current measurements for analog inputs were made with HDMI/analog simultaneous mode disabled (User Map Register 0xBA, Bit 7, programmed with Value 0) and
with no HDMI sources connected to the part.
7
Typical current measurements were taken with nominal voltage supply levels and an SMPTE bar video pattern input. Maximum current measurements were taken
with maximum rating voltage supply levels and a MoiréX video pattern input.
8
Current measurements for HDMI inputs were made with a source connected to the active HDMI port and with no source connected to the inactive HDMI port.
9
Audio stream is an uncompressed stereo audio sampling frequency of fS = 48 kHz, and MCLKOUT = 256 fS.
10
The maximum IDVDDIO value for the HDMI RGB sampling @ 225 MHz appears lower than expected. This is due to the 1080p 12-bit deep color mode input used during
evaluation. In this mode, the input HDMI TMDS clock has a frequency of 222.75 MHz; however, the output pixel clock is stepped down to 148.5 MHz to account for the
extra bits of data. DVDDIO power is proportional to the output pixel clock, therefore the stepping down of the output pixel clock data in 1080p 12-bit deep color
mode results in lower than expected IDVDDIO.
11
Analog current measurements for CVBS were made with only ADC0 powered up; for RGB, with only ADC0, ADC1, and ADC2 powered up; for SCART FB, with all ADCs
powered up; and for HDMI mode, with all ADCs powered off.
12
The terminator supply current may vary with the HDMI source in use.
