(4) For a full description of the SPEEDCTRL speed register configuration, see the description of the CONTROL_PROG_IO1 configuration

registers in System Control Module / Programming Model / Feature Settings section of the AM/DM37x Multimedia Device Technical

Reference Manual (literature number SPRUGN4).

(5) Rise and fall times are specified for (0.3 * vdds) to (0.7 * vdds).

(6) For capacitive load from 100 pF to 400 pF, fall time should be linearly interpolated:

tFmin = (1 + (Load – 100 pF) / 300 pF) * 10 ns

tFmax = (1 + (Load – 100 pF) / 300 pF) * 40 ns

(7) VIH is the voltage at which the receiver is required to detect a high state in the input signal.

(8) VIL is the voltage at which the receiver is required to detect a low state in the input signal. VIL is larger than the maximum single-ended

line voltage during HS transmission. Therefore, both LP receivers will detect low during HS signaling.

(9) This value includes a ground difference of 50 mV between the transmitter and the receiver, the status common-mode level tolerance

and variations below 450 MHz.

(10) Common mode is defined as the average voltage level of DX and DY: VCM = (V(DX) + V(DY))/2. Common mode ripple may be due to

rise-fall time and transmission line impairments in the PCB.

(11) Value when driving into differential load impedance anywhere in the range 80 to 125

Ω.

(12) ULPM stands for Ultra Low Power Mode.

(13) UI = 1 / (2 * fh), where fh is the fundamental frequency of HS data transmission. For example, for 800 Mbps fh is 400 MHz.

(14) vdda_x can be vdda_csiphy1 or vdda_csiphy2 depending on the interface used.

(15) At minimum load.

(16) At maximum load. Caution: This creates EMI parasitics up to 1.2 ns.

(17) For more information about IOH / IOL values, see one of the tables in the Ball Characteristics section, column

“BUFFER DRIVE

STRENGTH (mA)

”.

(18) No VOL specifications are applicable in Standard mode.

(19) For associated CBC and CUS balls, please refer to the Section 2.4, Multiplexing Characteristics table.
