CrystalLAN™ 100BASE-X and 10BASE-T Transceiver
This active high input initializes the CS8952, and causes the CS8952 to latch the input signal on the
following pins: COL/PHYAD0, CRS/PHYAD2, RX_ER/PHYAD4/RXD4, 10BT_SER, BP4B5B, BPALIGN,
BPSCR, ISODEF, REPEATER, RXD[1]/PHYAD1, and RXD[3]/PHYAD3.
A 25 MHz crystal should be connected across pins XTAL_I and XTAL_O. If a crystal is not used, a
25 MHz CMOS level clock may be connected to XTAL_I and XTAL_O left open.
NOTE: The XTAL_I pin capacitive load may be as high as 35pF. Any external clock source connected to this
pin must be capable of driving larger capacitive loads.
These seven pins are reserved and should be tied to VSS.
These pins provide power to the CS8952 MII interface. Typically VDD_MII will be either +5V or +3.3V.
These pins provide power to the CS8952 core. Typically, VDD should be +5V.
These pins provide a ground reference for the CS8952.
