CrystalLAN
100BASE-X and 10BASE-T Transceiver
TXSLEW[1:0] - Transmit Slew Rate Control. Input, Pins 61 and 60.
These three-level pins allow adjustment to the rise and fall times of the 10BASE-TX transmitter output
waveform. The rise and fall times are symmetric.
Media Interface Pins
RX+, RX- - 10/100 Receive. Differential Input Pair, Pins 91 and 92.
Differential input pair receives 10 or 100 Mb/s data from the receive port of the transformer primary.
TX+, TX- - 10/100 Transmit. Differential Output Pair, Pins 80 and 81.
Differential output pair drives 10 or 100 Mb/s data to the transmit port of the transformer primary.
RX_NRZ+, RX_NRZ- - FX Receive. Differential Input Pair, Pins 6 and 7.
PECL output pair receives 100 Mb/s NRZI-encoded data from an external optical module.
SIGNAL+, SIGNAL- - Signal Detect. Differential Input Pair, Pins 9 and 8.
PECL input pair receives signal detection indication from an external optical module.
TX_NRZ+, TX_NRZ- - FX Transmit. Differential Output Pair, Pins 5 and 4.
PECL output pair drives 100 Mb/s NRZI-encoded data to an external optical module.
General Pins
CLK25 - 25 MHz Clock. Output, Pin 17.
A 25 MHz Clock is output on this pin when the CS8952 is configured to use an external reference
transmit clock in TX_CLK IN MASTER mode. See the pin description for the Transmit Clock Mode
Initialization pin (TCM) for more information on TX_CLK operating modes.
CLK25 may also be enabled regardless of the TCM pin state by clearing bit 7 of the PCS Sub-layer
Configuration Register (address 17h).
RES - Reference Resistor. Input, Pin 86.
This input should be connected to ground with a 4.99 k
+/-1% series resistor. The resistor is needed
for the biasing of internal analog circuits.
