Product Overview
The DP83867IR is a Texas Instruments 10/100/1000 Ethernet PHY transceiver in the Signal_Chain category. It is IEEE 802.3 compatible for 10BASE-Te, 100BASE-TX, and 1000BASE-T links, with MAC interface support determined by package: MII/GMII/RGMII on the industrial PAP option and RGMII on the industrial RGZ option.
Package choices include a PAP 64-pin HTQFP measuring 12 mm x 12 mm and an RGZ 48-pin VQFN measuring 7 mm x 7 mm. The RGZ package includes an exposed pad with DAP tied to GND. Industrial-grade DP83867IRRGZ and DP83867IRPAP versions are specified for -40°C to +85°C operation.
Interface timing features include RGMII transmit latency below 90 ns, receive latency below 290 ns, and 16 programmable RX/TX RGMII delay modes. Clock-related facts include 25 MHz or 125 MHz synchronized clock output, 2.5 MHz and 25 MHz MII TX_CLK modes, 125 MHz nominal GTX_CLK, and RX_CLK options of 2.5 MHz, 25 MHz, or 125 MHz by link mode.
