5.19 TPS99000-Q1 SPI Interface Timing Requirements
The DLPC23x-Q1 ASIC to TPS99000-Q1 interface consists of an SPI serial interface.
| (1) | MIN | MAX | UNIT | ||
|---|---|---|---|---|---|
| fclock | Clock frequency, PMIC_SPI_CLK | 9.998 | 30.006 | MHz | |
| tp_clkper | Clock period, PMIC_SPI_CLK (50% reference points) | 33.3 | 100 | ns | |
| tp_wh | Pulse duration high, PMIC_SPI_CLK (50% reference points) | 11.5 | ns | ||
| tp_wl | Pulse duration low, PMIC_SPI_CLK (50% reference points) | 11.5 | ns | ||
| tt | Transition time – all input signals | 20% to 80% reference points | 6 | ns | |
| tp_su | Setup time – PMIC_SPI_DIN valid before PMIC_SPI_CLK falling edge (50% reference points) | 7.0 | ns | ||
| tp_h | Hold time – PMIC_SPI_DIN valid after PMIC_SPI_CLK falling edge | 50% reference points | 0.0 | ns | |
| tp_clqv | PMIC_SPI_DOUT output delay (valid) time (with respect to falling edge of PMIC_SPI_CLK or falling edge of PMIC_SPI_CSZ0) | –3.0 | 3.0 | ns | |
(1) The DLPC23x-Q1 communicates with the TPS99000-Q1 using a slight variant of SPI Transfer Mode 0 (that is, clock polarity = 0, clock phase = 0). Instead of capturing MISO data on the clock edge opposite from that used to transmit MOSI data, the DLPC23x-Q1 captures MISO data on the same clock edge used to transmit the next MOSI data. As such, the DLPC23x-Q1 SPI interface to the TPS99000-Q1 requires that MISO data from the TPS99000-Q1 remain active until the end of the full clock cycle to allow the last data bit to be captured. This is shown in Figure 5-12.
