... Reset The CX28380 supports three reset methods: power-on reset, hard reset initiated by the RESET pin, and soft reset initiated by the RESET bit in the Global Configuration Register [GCR; addr 01]. In Host Mode, all three reset methods produce the same results as listed below. In Hardware Mode, power-on reset and hard reset produce the same results as shown, and soft reset is not applicable ...
Page 22
... Power-on Reset An internal power-on reset process is initiated during power-up. When VDD has reached approximately 2.6 V, the internal reset process begins and continues for 300 ms maximum if REFCLK is applied. If REFCLK is not present, the CX28380 remains in the reset state. 2.2.4.2 Hard Reset Hard reset is initiated by bringing the RESET pin active (low). Once initiated, the internal reset process completes in 5 µ ...

... XTIP[n] and XRING[n]. When a shorted line is detected, transmit monitor and protection circuits reduce the output current level to less than 50 mA RMS. The standard transmit transformer for the CX28380 has a turns ratio of 1:2 (chip-side:line-side). To minimize power consumption, an alternate 1:1.36 turns ratio transformer can be used in an unterminated configuration. ...
Page 32
... Resistors (Rs) in series with Tx TIP and Tx RING line connections are sometimes used with surge protection circuits. Without compensation, the addition of these resistors decreases the transmit pulse amplitude. The CX28380 provides an option in Host Mode to boost the output level if resistors are installed. Compensation is optimized for the use of 5.6 Ω Rs values. In Hardware Mode, these resistors are required. ...
