PM8353 Overview
The is a Quad PHYsical layer transceiver ideal for systems requiring large numbers of point-to-point gigabit links. It provides four individual serial channels capable of operation at up to 1.25 Gbps each, which may be grouped together to form a single 5.0 Gbps bidirectional link. Each of the four primary channels has a corresponding secondary channel that can be enabled via the MDC/MDIO serial interface.
PM8353 Key Features
- Four independent 1.0-1.25 Gbit/s transceivers
- Four secondary channels to support channel redundancy
- Ultra low power operation: 1.25 Watt typical
- Integrated serializer/deserializer, clock synthesis, clock recovery, and 8B/10B encode/decode logic
- Physical Coding Sublayer (PCS) logic for Gigabit Ethernet
- Selectable 8-bit, 10-bit, or IEEE 802.3z GMII parallel interface
- Optional Receive FIFOs which synchronize ining data to local clock domain
- 100-156 MHz Single Data Rate (SDR) parallel transmit interface with clock forwarding
- 100-125 MHz SDR parallel receive interface
