Note 1: At power up, the Ethernet chip operates from the 125 MHz clock. The internal frequency can be dropped to 25 MHz via the external EEPROM. This clock rate selection is for new chip Rev-A2 only.
7.2 Board Reset
The KSZ88XX-16 MQL Demo Board generates a reset signal from the reset circuitry during power up. It also provides a push button S4 reset circuit to reset the whole Demo Board. At power up, the board is automatically reset. User can also press reset button S4
on the board for a manual reset. After any reset, the LED1 and LED2 flash to indicate the power on self-test, also the LCD module shows the HW/SW board status and system set up result.
7.3 Clock Scheme
The Ethernet chip reference clock is provided from external 25 MHz crystal (Y1). The crystal is connected to the X1 and X2 pins on the KSZ88XX-16 MQL. This 25 MHz clock is specified as +3.3V tolerant, +/- 50 ppm. If an oscillator is used, X1 connects to a 3.3V tolerant oscillator and X2 is no connection.
The M16C microcomputer receives two references clocks, one is the 12 MHz crystal, connected to Xout/Xin pins, the other is the 32 KHz crystal, connected to XCout/XCin pins. Both clocks are specified as +5.0V tolerant, +/- 100 ppm.
7.4 ESD Protection circuit
The Demo Board contains two levels of ESD protection circuitry (Option).
The first level of ESD protection uses D1/D2 (GBLC03C) for LAN port 1 RX/TX pairs and D3/D4 (GBLC03C) for LAN port 2 RX/TX pairs before the T1/T2 transformers.
The second level of ESD protection uses U3 hybrid (SRV05-4) for LAN port 1 RX/TX pairs and U4 hybrid (SRV05-4) for LAN port 2 RX/TX pairs after the T1/T2 transformers.

7.5 POT1 and POT2
Adjust POT1 to change the contrast of the LCD display module.
Adjust POT2 to change the UDP receive value when streaming from Demo Board to PC on the demo software.

Bus Interface Connection

The KSZ88XX-16 MQL Demo Board provides a 16-bit bus interface to the M16C microcomputer. The external EEPROM is used to set up the bus width of the Demo Board. Figure 9 shows the 16-Bit Asynchronous Interface.

External Interfaces

9.1 LAN Interfaces
9.1.1 Two 10/100Base-TX Fast Ethernet Ports
The LAN interfaces on the KSZ88XX-16 MQL are connected to a transformer (T1, T2) with 50ohm differential termination resistors for each port. The line side of the transformer is connected to the RJ-45 connectors (J1, J2) for LAN port 1 and port 2.
9.1.2 One 100Base-FX Fast Ethernet Port
With the additional circuitry, the LAN port 1 interface can also support 100Base-FX with a fiber optic module (U5). The 100Base-FX fiber optic mode is supported by KSZ886X16 MQL only. To support fiber mode, 0 ohm resistors (R63, R65, R67, R69) need to be populated and 0 ohm resistors (R64, R66, R68, R70) need to be removed.
There is a 3-pin jumper (JP4) to select either +3.3V (pin 1-2) or +5V (pin 2-3) for the fiber optic module (U5) power.
9.2 UART
The KSZ88XX-16 MQL Demo Board provides an UART serial interface (P1) for serial data communication between hyper terminal and Demo Board.
9.3 ICD (In-Circuit Debugger)
This In-Circuit Debugger interface (J3) is used for USB debugger and FoUSB programmer downloading.
9.4 Power Jack
A +5V DC input is connected to the power jack J4 to supply the Demo Board.
9.5 Power Supply and Test Point
The Demo Board is supplied with +5.0V DC power through a jack (J4) and converted to +3.3V with a Micrel +3.3V voltage regulator (U9, MIC37152BR). The KSZ88XX-16 MQL contains an internal +1.2V LDO, to provide its core, analog and PLL voltages.
