RCC611

The RCC611 is a monolithic 125 Megabaud CMOS transceiver chip. RCC611 integrates a complete phase-locked loop clock and data recovery, a phase locked loop clock synthesizer, a 5:1 Serializer, a 1:5 Deserializer, 4B/5B Encoder, 5B/4B Decoder, auto-negotiation and a management interface for link control and status. It also includes scrambler, descrambler for twisted pair copper applications in compliance with FDDI TP-PMD specifications. In conjunction with RCC613 twisted pair transceiver, the chipset can be used for driving with category 5 unshielded twisted pair cable and Type 1 shielded twisted pair cable. The chip meets the physical layer interface requirements of the 100 Base-X Fast Ethernet and FDDI standards. The RCC611 chip operates with a single, +5v power supply.

The features of RCC611 can be summarized as (1)100 Mbps/125 Mbaud data rates; (2)low power 0.6 micron CMOS technology; (3)PLL Clock and data recovery; (4)clock synthesizer; (5)auto-negotiation; (6)4b/5b encode/decode; (7)FDDI TP/PMD scrambling/descrambling; (8)management interface for control/status; (9)link pulse signalling; (10)conforming to MH interface of IEEE 100baseTX fast ethernet standard(P802.3u/D3); (11)low power dissipation-600 mW typical; (12)single power supply: +5v; (13)PECL compatible serial data inputs/outputs; (14)support for external 10 Mbps PHY; (15)100 pin PQFP (20mm x 14mm x 2.7 mm).

The absolute maximum ratings of RCC611 are (1)storage temperature range: -65 to 150°C; (2)junction temperature range: -55 to 150°C; (3)lead temperature range (soldering, 10 seconds):300°C; (4)positive power supply, voc, Arxvcc, Asxvcc us: 0 to 6 V; (5)voltage applied to any inputs: -1 to 6V; (6)voltage applied to any PECL inputs : -1 to 6V; (7)voltage applied to any CMOS outputs: -1 to 6V; (8)voltage applied to any PECL outputs: -1 to 6V; (9)current from any CMOS outputs: -50 to 50 mA; (10)current from any PECL outputs: -50 to 50 mA("Absolute maximum ratings" are those beyond which the safety of the device cannot be guaranteed. They are not meant imply that the devioe should be operated at these limits. If the device is subjected to the limits in the absolute maximum ratin for extended periods, its reliability may be impaired. The tables of Electrical Characteristics provide conditions for actual device operation. )
