BCM5220/BCM5221 Application Note
The BCM5221 includes the following features: Auto-MDIX switching capability Glueless media conversion capability (100BASE-TX to 100BASE-FX) and Cable Quality Monitoring capability The BCM5221 is actually a 2 5V device that includes on-chip 3 3V to 2 5V regulators making it suitable for 3 3V system |
Does bcm5221 perform auto-negotiation?
Auto-Negotiation Capability. The BCM5221 is capable of performing IEEE auto-negotiation, and returns a 1 when bit 4 of the Status register is read, regardless of whether the auto-negotiation function has been disabled. Link Status.
How do I drive the bcm5221 clock input?
The BCM5221 clock input can be driven two ways: internal crystal oscillator or external oscillator. To take advantage of the internal oscillator, attach a 25-MHz crystal between the XTALI and XTALO pins. Connect 27 pF capacitors from each pin to ground. Alternatively, a 50% duty cycle 25-MHz clock can be directly applied to the XTALI pin.
How does the bcm5221 perform a Mii read operation?
For the MII read operation, the BCM5221 drives the MDIO line during the TA and Data fields (the last 17 bit times). A final 65th clock pulse must be sent to close the transaction and cause a write operation. Table7 contains the MII register summary for the BCM5221.
What does bcm5221 do?
MDIX Manual Swap. When this bit is set to a 1, the BCM5221 forces its MDI TD+ and RD+ signals to be swapped. HP Auto-MDIX Disable. When this bit is set to a 1, then the BCM5221 disables the HP Auto-MDIX function.
