DISTINCTIVE CHARACTERISTICS
s Compatible with lEEE 802.3/Ethernet/Cheapernet specifications s Crystal/TTL oscillator-controlled Manchester encoder s Manchester decoder acquires clock and data within four bit times with an accuracy of ±3 ns s Guaranteed carrier and collision detection squelch threshold limits — Carrier/collision detected for inputs greater than –275 mV — No carrier/collision for inputs less than –175 mV s Input signal conditioning rejects transient noise — Transients <10 ns for collision detector inputs — Transients <20 ns for carrier detector inputs s Receiver decodes Manchester data with worst case ±19 ns of clock jitter (at 10 MHz) s TTL-compatible host interface s Transmit accuracy +0.
