Manufacturer:ON Description:3 4 COLLISION TRANSLATOR The Ethernet transceiver detects collisions on the coax ca- ble and generates a 10 MHz signal on the transceiver cable The SNIs collision translator asserts the collision detect output (COL) to the DP8390 controller when a 10 MHz sig- nal is present at the collision inputs The controller uses this signal to back off transmission and recycle itself The colli- sion detect output is de-asserted within 350 ns after the 10 MHz input signal disappears The collision differential inputs ( a and b) should be termi- nated in exactly the same way as the receive inputs The collision input also has a squelch circuit that rejects signals with pulse widths less than 8 ns (negative going) or with levels less than b175 mV Figure 10 illustrates the collision timing |
