Model: 88E1340S

Brand: Marvell

Date code: 21+

Package: BGA

The 88E1340S Gigabit Ethernet PHY (Physical Layer) chip is the latest product launched by Interstellar Jinhua. It is a brand new and genuine product.

Support 10/100/1000 QSGMII (Quad-Serial Gigabit Media Independent Interface) interface.

Support QSGMII interface for direct connection to MAC chip or SWITCH chip.

The QSGMII interface combines four SGMII interfaces with a rate of 1.25 Gbps into a differential signal with a rate of 5 Gbps.

The QSGMII interface reduces the number of pins connected to the MAC interface and reduces the overall power consumption.

The QSGMII MAC interface can be used as a copper network cable (electrical port) or optical fiber (optical port).

88E1340S can support the SGMII interface on the interface connected to the MAC, which is used for the application of an SGMII interface connected to the electrical interface.

The 88E1340S integrates termination resistors and capacitors for the MDI interface into the PHY. The integration of this resistor simplifies board layout and reduces board cost by reducing the number of external components. The new Marvell calibrated resistor program will meet and exceed Accuracy requirements of the IEEE 80 2.3 return loss specification.

The 88E1340S is fully compliant with IEEE 802.3 standards. Including PMD, PMA, PCS sublayers. Receivers that perform PAM3, 8B/10B, 4B/5B, MLT-3, NRZI, Manchester encoding/decoding, digital clock recovery, digital adaptive equalizer management functions of the data path, digital filtering of pulse shaping of line transmitters, auto-negotiation, etc.

The 88E1340S device supports Auto-MDI/MDIX at three speeds, making installation more convenient and reducing installation costs.

Support return mode for diagnostics/tests.

In a 15x15mm 196-pin TFBGA package.
