78Q2123R/F Description

Short technical summary and product information.

The 78Q2123R/F is part of the MicroPHY family, a compact 10BASE-T/100BASE-TX Fast Ethernet transceiver from Analog Devices / Maxim Integrated.

 

It features an integrated MII, ENDECs, scrambler/descrambler, dual-speed clock recovery, and full-featured auto-negotiation. The device includes 4 drivers and 4 receivers with full duplex capability, and a receiver hysteresis of 125 mV. It operates from a 3.0V to 3.6V supply, with a nominal 3.3V, and typical power consumption of 290 mW in low power mode.

 

The transceiver is housed in a 32-VFQFN exposed pad package (32-QFN-EP 5x5 mm) and designed for surface mount assembly. It operates over a commercial temperature range of 0°C to 70°C.
