AC Electrical Specifications
NOTES:
10. Measured from V
11. I
12. TX_PE must be inactive before going active to generate a new packet.
13. I
14. RX_PE must be inactive at least 3 MCLKs before going active to start a new CCA or acquisition.
15. RX_PE active to inactive delay to prevent next RX_CLK.
16. Assumes RX_PE inactive after last RX_CLK.
17. MD_RDY programmed to go active after SFD detect. (measured from I
18. MD_RDY programmed to go active at MPDU start. Measured from first chip of first MPDU symbol at I
19. Minimum time to insure Reset. RESET must be followed by an RX_PE pulse to insure proper operation. This pulse should not be used for first
20. Delay from TXCLK to inactive edge of TXPE to prevent next TXCLK. Because TXPE asynchronously stops TXCLK, TXPE going inactive within
TX_CLK to TX_PE Inactive (11Mbps)

Setup RXD to RX_CLK
RX_CLK to RX_PE Inactive (1Mbps)
RX_CLK to RX_PE Inactive (2Mbps)
RX_CLK to RX_PE Inactive (5.5Mbps)
RX_CLK to RX_PE Inactive (11Mbps)
RX_PE inactive to MD_RDY Inactive
Last Chip of SFD in to MD_RDY Active
RX Delay
RESET Width Active
RX_PE to CCA Valid
RX_PE to RSSI Valid
SCLK Clock Period
SCLK Width Hi or Low
Setup to SCLK + Edge (SD, SDI, R/W, CS)
Hold Time from SCLK + Edge (SD, SDI, R/W, CS)
SD Out Delay from SCLK + Edge
SD Out Enable/Disable from R/W
TEST 0-7, CCA, ANTSEL, TEST_CK from MCLK
8. AC tests performed with C
9. Not tested, but characterized at initial design and at major process/design changes.
