Suffix Explanation
- RTL8201FL: Main model of industrial-grade 100M Ethernet PHY chip
- VB: Supports MII, RMII and SNI three MAC host interfaces
- CG: LQFP-48 surface mount packaging mark, factory default tape-and-reel packaging for automatic SMT assembly
1. Core Protocol & Interface Specifications
- Fully complies with IEEE 802.3 10BASE-T and IEEE 802.3u 100BASE-TX Ethernet standards, and supports IEEE 802.3az EEE energy-efficient Ethernet power saving protocol
- Three optional MAC connection modes: standard MII, reduced pin count RMII and serial SNI interface
- Built-in Auto-MDI/MDIX automatic cable identification and polarity reversal function, no need to distinguish straight or crossover network cables
- Supports automatic negotiation to match 10M/100M rate and full-duplex/half-duplex working mode
- Reserved PECL external fiber interface, which can be matched with 100Base-FX optical transceiver to realize optical fiber network transmission
- Equipped with standard MDC/MDIO management bus for register configuration, status reading and parameter adjustment by main controller
2. Electrical Power & Performance Parameters
- Single 3.3V power supply input, internal integrated voltage regulator supports 2.5V core operation, compatible with 5V tolerant I/O signals
- Adopts advanced CMOS low-power process, with multiple power management modes including deep power-down and link idle energy saving to reduce standby power consumption
- On-chip DSP adaptive equalization technology enhances anti-interference and long-distance transmission capability, stably transmits 100 meters via Category 5 network cable
- Supports network wake-on-LAN remote wake-up function and repeater working mode
- External 25MHz crystal oscillator is used as the reference clock source, and multiple LED pins are reserved to indicate link status, speed and duplex state
