5.20 TPS99000-Q1 AD3 Interface Timing Requirements
The DLPC23x-Q1 ASIC to TPS99000-Q1 AD3 interface is used to retrieve ADC
measurements from the TPS99000-Q1. The interface is similar to SPI and includes a
clock, MOSI, and MISO signal.
| (1)(2)(3) | MIN | MAX | UNIT | ||
|---|---|---|---|---|---|
| fclock | Clock frequency, PMIC_AD3_CLK | 29.326 | 30.006 | MHz | |
| tp_clkper | Clock period, PMIC_AD3_CLK (50% reference points) | 33.327 | 34.100 | ns | |
| tp_wh | Pulse duration high, PMIC_AD3_CLK (50% reference points) (Referenced to tp_clkper) | 40% | |||
| tp_wl | Pulse duration low, PMIC_AD3_CLK (50% reference points) (Referenced to tp_clkper) | 40% | |||
| tt | Transition time – all input signals | 20% to 80% reference points | 6 | ns | |
| tp_su | Setup time –
PMIC_AD3_MISO valid before PMIC_AD3_CLK falling edge (50% reference points) | 14.5 | ns | ||
| tp_h | Hold time –
PMIC_AD3_MISO valid after PMIC_AD3_CLK falling edge (50% reference points) | 0 | ns | ||
| tp_clqv | PMIC_AD3_MOSI
output delay (valid) time (with respect to falling edge of
PMIC_AD3_CLK) (50% reference points) | –2.0 | 2.0 | ns | |
(1) PMIC_AD3_MOSI ((DLPC23x-Q1) Output / (TPS99000-Q1) Input) is transmitted on the
falling edge of PMIC_AD3_CLK.
(2) PMIC_AD3_MISO ((DLPC23x-Q1) Input / (TPS99000-Q1) Output) is captured on the
rising edge of PMIC_AD3_CLK.
(3) PMIC_AD3_CLK is used as the primary TPS99000-Q1 system clock in addition to supporting the AD3 interface.
