概述

Description

KSZ8794CNXCC-TR is a Microchip (Micrel) 4-port Ethernet switch IC. It combines four integrated MAC/PHY interfaces with a switch fabric, giving a CPU/management port plus three switch ports in one device. It supports 10/100/1000BASE-T and features MAC address learning, VLAN tagging (802.1Q), QoS, and basic frame filtering. Management is via a serial management interface (MDIO/MDC). It’s intended for embedded designs (routers, gateways, IP cameras, industrial controllers) that need a compact, low-pin Ethernet switch. The CNXCC part describes the package variant, and TR indicates tape‑and‑reel packaging.

Features

KSZ8794CNXCC-TR is a 4-port Ethernet switch PHY with integrated MACs. Key features include:
- 4x 10/100/1000BASE-T ports with integrated MAC/PHY
- IEEE 802.3 compliant; auto-negotiation and auto-MDIX on all ports
- Non-blocking switch fabric for full throughput
- VLAN support (802.1Q) with QoS capabilities (priority queuing, traffic management)
- Jumbo frames support (large frame size for efficiency)
- MAC address table with learning, filtering, and broadcast storm protection
- Management via MDIO/MDC interface for host control and configuration
- Power-management options and energy-efficient features
- Packaging: CNXCC with TR (Tape & Reel) option
Note: exact QoS/timestamping details and frame-size limits can vary by revision; consult the datasheet for precise specifications.

Package

KSZ8794CNXCC-TR is in a QFN-48 (48-pin, leadless) package, Tape & Reel (TR).

Pinout

- Pin count: 48 pins (LQFP-48 package; TSOP/TQFP variants exist but KSZ8794CNXCC-TR is a 48-pin device).
- Function: Quad-port Ethernet switch (4 x 10/100/1000BASE-T) with integrated MAC/PHY and switch fabric; provides four Ethernet ports and a management/CPU interface (MDIO/MDC) for control.

Manufacturer

The KSZ8794CNXCC-TR is manufactured by Microchip Technology Inc. Microchip is a global semiconductor company (American) that designs and manufactures embedded control solutions, including microcontrollers, analog/memory devices, and networking ICs such as Ethernet PHYs.

Application

KSZ8794CNXCC-TR is a 4‑port Gigabit Ethernet switch IC (embedded networking). Typical application areas: routers/gateways, IP cameras and video surveillance, network printers and POS terminals, digital signage, industrial automation and data acquisition, set‑top boxes, and edge/compact network devices requiring a small, managed Ethernet switch.
