2 / 2 page ![]() Common features > Independent SerDes channels with full-duplex differential data links > Configurable as a single channel device to provide redundant transmit and receive serial links > Selectable speed range: 1.25 Gbaud or 0.625 Gbaud > Internal 8B/10B encoder/decoders > Source synchronous parallel data input interfaces > Selectable source-synchronous or source-centered timing on receiver interface > Links drive 50-ohm or 75-ohm media (100- or 150-ohm differential), backplane or cable > Link inputs have on-chip receiver link termination and are “hot-swap” compatible > Low power: <0.6 W, under typical conditions, while operating in backplane mode with all transceivers at full speed > Unused transceiver channels may be individually disabled to reduce power consumption > IEEE Std 1149.1 JTAG support and full-speed built-in self test functions Backplane application features > Link-to-link synchronization supports aligned, multi-channel, word transfers. Synchronization mechanism tolerates up to 40 bit-times of link-to-link media delay skew > Supports Disparity Based Word Sync Events for compatibility with legacy transceivers > Selectable COMMA code group alignment mode enables aligned or unaligned transfers Ethernet friendly features > GMII, TBI, RGMII or RTBI data interface options > COMMA code group alignment in receivers > Provides the PCS and PMA layers for Ethernet PHYs as specified in IEEE Std. 802.3-2002 > MDIO slave interface and registers as defined in IEEE Std. 802.3-2002 is fully supported > MDIO interface is available in all operating modes Technical specifications > All channels have: • 8B/10B encoder/decoder that can be enabled or bypassed in Ten-Bit Interface (TBI) mode • Clock generation/recovery • Independent 8/10-bit or 4/5-bit system I/F with parallel-to-serial, serial-to-parallel conversion > Transmit data clock is selectable between per-channel transmit clock or channel ‘A’ transmit clock > Received data may be clocked at the recovered clock or the reference clock frequencies > Half frequency, split-phase recovered clock in TBI (10-bit) mode > Transceiver Links operate over 50-ohm or 75-ohm media (100- or 150-ohm differential) for lengths of up to 1.5 meters of FR-4 board/back-plane, or 10 meters of coax > No external loop filter components required > System BIST test modes with error counter > Loopback BIST isolated from link inputs and outputs > IEEE Std 1149.1 JTAG boundary scan support > LVPECL differential reference clock input with single-ended LVTTL reference clock input option > Two single ended buffered Ref Clock outputs provided for associated logic interfaces > Frequency offset tolerance between transmitter and receiver in excess of ± 250 ppm Freescale™ and the Freescale logo are trademarks of Freescale Semiconductor, Inc.
