Min

Typ

Max

Unit

TLPX

Transmitted length of any LP state period

TCLK-PREPARE

Time that the transmitter drives the clock lane LP-00

line state immediately before the HS-0 line state,

starting the HS transmission

TCLK-PREPARE

+ TCLK-ZERO

TCLK-PREPARE + time that the transmitter drives the

HS-0 state prior to starting the clock

300

TCLK-PRE

Time that the HS clock must be driven by the

transmitter prior to any associated data lane beginning

the transition from LP to HS mode

UI(2)

TCLK-POST

Time that the transmitter continues to send HS clock

after the last associated data lane transitioned to

LP mode

62 + 52 × UI

TCLK-TRAIL

Time that the transmitter drives the HS-0 state after

the last payload clock bit of an HS transmission burst

THS-PREPARE

Time that the transmitter drives the data lane LP-00

line state immediately before the HS-0 line state

starting the HS transmission

40 + 4 × UI

85 + 6 × UI

THS-PREPARE

+ THS-ZERO

THS-PREPARE + time that the transmitter drives the

HS-0 state prior to transmitting the sync sequence

145 + 10 × UI

THS-TRAIL

Time that the transmitter drives the flipped differential

state after last payload data bit of a HS transmission

burst

Max

(n × 8 × UI,

60 + n × 4 × UI)

THS-EXIT

Time that the transmitter drives LP-11 following

a HS burst

100

TREOT

30%-85% rise and fall time

TEOT

Transmitted time interval from the start of THS-TRAIL or

TCLK-TRAIL, to the start of the LP-11 state following a

HS burst

105 + n ×

12 × UI

1. Evaluated by characterization. Not tested in production.

2. UI (unit interval) equals to the duration of any HS state on the clock lane.
