Low-Power Gigabit Ethernet serializer/deserializer
Texas Instruments has today introduced the industry's smallest low-power, single-channel Gigabit Ethernet (GbE) serializer/deserializer (SerDes) device, enabling higher densities in data communications and telecommunications equipment. The new interface device combines a small 6-mm x 6-mm package with low power consumption at 200 mW 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 data rates from 600 Mbps to 1.3 Gbps, including GbE and CPRI data rates. 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. Other key features include the following:
* Support for 10-bit interface
* Industrial temperature range from -40°C to 85°C
* IEEE 802.3 GbE compliant
* Comprehensive, built-in testability
* 2.5-V supply voltage for lowest power operation
* 3.3-V tolerance on LVTTL inputs
* Hot plug protection
The addition of the TLK1221 SerDes device complements Texas Instruments' broad interface product offering including families of products for M-LVDS, LVDS, PECL, RS-485, 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 $3.25 each in 1,000-piece quantities.
