| 38 || XTAL_IN || I || Reference Clock. 25 MHz ± 50 ppm tolerance crystal reference or oscillator input.
NOTE: If AVDDC is tied to 1.8V, then the XTAL_IN pin is not 2.5V/3.3V tolerant.
If AVDDC is tied to 2.5V, then the XTAL_IN pin is not 3.3V tolerant.
|-
| 39 || XTAL_OUT || O || Reference Clock. 25 MHz ± 50 ppm tolerance crystal reference. When the
XTAL_OUT pin is not connected, it should be left floating.

Gigabit LAN[edit | edit source]

The PS3 has 1 Gigabit Ethernet port. The port accepts Auto-MDIX (automatic medium-dependent interface crossover), so no need for special crosscables when hooking up the PS3 direct to the PC.

Gigabit LAN chips used[edit | edit source]

A sample of the GbLAN chips in different PS3 models:

Ports Size Speed Voltage Packaging Manufacturer Serial Number Description
8 (3 used) 20x20mm Xtal X3501: 25MHz 3.3V/1.9V/1.2V 144-pin TQFP Marvell Alaska 88E6108-LAR1 Used in earlier models (up to CECHGxx/SEM-001)
? ? ? ? ? Marvell Alaska 88E6106-LKJ1 Used in later models (CECHHxx/DIA-001)
? ? ? ? ? ? ? DIA-002 (CECHJxx, CECHKxx)

Jumbo frames[edit | edit source]

From Linux perspective (under OtherOS <=3.15), the old drivers set the MTU to 2308, while newer versions set the MTU of 1518. This could be a hypervisor restriction (needs research). 

MTU is set with vsh using syscall net_ioctl (libnet)

On 3.41 firmware, with a modified ps3_gelic driver, frames of 1624 bytes can be sent and frames of 1628 bytes can be received.
