Serdes shrinks gigabit comms

Industry's smallest low-power, single-channel gigabit Ethernet serdes enables higher densities in datacommunications and telecommunications equipment.

Texas Instruments has released a device it reckons is the industry's smallest low-power, single-channel gigabit Ethernet serdes, enabling higher densities in datacommunications and telecommunications equipment.

The new interface device combines a small 6 x 6mm package with low power consumption at 200mW to reduce board size and complexity and save power in Ethernet passive optical networks (EPON), GbE switches/routers and wireless basestations.

The TLK1221 supports high-speed, full-duplex, point-to-point data transmissions at datarates from 600Mbit/s to 1.3Gbit/s, including GbE and CPRI datarates.

This gives designers the flexibility and ease to upgrade their systems using this one device.

The device also eliminates the need for external filter capacitors to further simplify design and reduce cost.

The addition of the TLK1221 serdes device complements Texas Instruments' broad interface product offering including families of products for M-LVDS, LVDS, PECL, RS485, PCI-Express and additional gigabit Ethernet SerDes devices.

The TLK1221 is available now in a 40-pin quad flat no lead (QFN) lead-free package and is priced at US $3.25 each in 1000-piece quantities.
