20 / 57 page  CC1070 SWRS043A Page 20 of 54 Parameter Symbol Min Max Unit Conditions PCLK, clock frequency FPCLK 10 MHz PCLK low pulse duration TCL,min 50 ns The minimum time PCLK must be low. PCLK high pulse duration TCH,min 50 ns The minimum time PCLK must be high. PSEL setup time TSS 25 ns The minimum time PSEL must be low before positive edge of PCLK. PSEL hold time THS 25 ns The minimum time PSEL must be held low after the negative edge of PCLK. PSEL high time TSH 50 ns The minimum time PSEL must be high. PDI setup time TSD 25 ns The minimum time data on PDI must be ready before the positive edge of PCLK. PDI hold time THD 25 ns The minimum time data must be held at PDI, after the positive edge of PCLK. Rise time Trise 100 ns The maximum rise time for PCLK and PSEL Fall time Tfall 100 ns The maximum fall time for PCLK and PSEL Note: The setup and hold times refer to 50% of VDD. The rise and fall times refer to 10% / 90% of VDD. The maximum load that this table is valid for is 20 pF. Table 11. Serial interface, timing specification 9.2 Signal Interface The CC1070 can be used with NRZ (Non- Return-to-Zero) data or Manchester (also known as bi-phase-level) encoded data. The data format is controlled by the DATA_FORMAT[1:0] bits in the MODEM register. CC1070 can be configured for three different data formats: Synchronous NRZ mode During transmit operation, the CC1070 provides the data clock at DCLK and DI is used as data input. Data is clocked into CC1070 at the rising edge of DCLK. The data is modulated at RF without encoding. See Figure 8. Synchronous Manchester encoded mode During transmit operation, the CC1070 provides the data clock at DCLK and DI is used as data input. Data is clocked into CC1070 at the rising edge of DCLK and should be in NRZ format. The data is modulated at RF with Manchester code. The encoding is done by CC1070. In this mode the effective bit rate is half the baud rate due to the coding. As an example, 19.2 kBaud Manchester encoded data corresponds to a 9.6 kbps. See Figure 9. Transparent Asynchronous UART mode During transmit operation, DI is used as data input. The data is modulated at RF without synchronization or encoding. In this mode, the DCLK pin is not active and can be set to a high or low level by DATA_FORMAT[0]. See Figure 10. |
