Configuration Registers Read Operation Table 5-1. Serial Interface, Timing Specification(1) PARAMETER MIN MAX UNIT CONDITION FPCLK PCLK, clock frequency 10 MHz TCL,min PCLK low pulse duration 50 ns The minimum time PCLK must be low. TCH,min PCLK high pulse duration 50 ns The minimum time PCLK must be high. The minimum time PSEL must be low before TSS PSEL setup time 25 ns positive edge of PCLK. The minimum time PSEL must be held low THS PSEL hold time 25 ns after the negative edge of PCLK. TSH PSEL high time 50 ns The minimum time PSEL must be high. The minimum time data on PDI must be ready TSD PDI setup time 25 ns before the positive edge of PCLK. The minimum time data must be held at PDI, THD PDI hold time 25 ns after the positive edge of PCLK. Trise Rise time 100 ns The maximum rise time for PCLK and PSEL Tfall Fall time 100 ns The maximum fall time for PCLK and PSEL (1) 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. 5.6 Signal Interface The CC1020 can be used with NRZ (Non-Return-to-Zero) data or Manchester (also known as bi-phase- level) encoded data. CC1020 can also synchronize the data from the demodulator and provide the data clock at DCLK. The data format is controlled by the DATA_FORMAT[1:0] bits in the MODEM register. CC1020 can be configured for three different data formats: Synchronous NRZ mode, Transparent Asynchronous UART mode, and Synchronous Manchester encoded mode.
