Press Release Summary:
Capable of 3.3 and 2.5 V operation, LVDS20 and LVP20 help ensure signal and clock integrity in communications applications and can also serve as translators. Both connect high-speed differential receiver and driver as repeater. Receiver accepts low-voltage PECL signals at rates to 4 Gbps and repeats them as LVDS (LVDS20) or LVPECL (LVP20) output signals. Differential signal path through the devices minimizes EMI and limits added jitter.

TI Introduces High-Speed LVDS and LVPECL Repeaters/Translators
Tiny Devices Offer Low Jitter and Low Power for Communications Equipment
DALLAS (Sept. 22, 2005) - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a 4-Gbps low-voltage differential signaling (LVDS) and low-voltage pseudo emitter-coupled logic (LVPECL) repeater and translator. Featuring low total jitter of 45 ps, the devices help ensure signal and clock integrity in various communications applications including high-speed network routing, wireless base stations and 622-MHz central office clock distribution, and they can also serve as translators in an array of consumer applications. (See www.ti.com/sc05196.)
Both the SN65LVDS and SN65LVP20 connect a high-speed differential receiver and driver as a repeater. The receiver accepts low-voltage PECL signals at rates up to 4 Gbps and repeats them as LVDS (LVDS20) or LVPECL (LVP20) output signals. The differential signal path through the devices minimizes electromagnetic interference (EMI) and limits added jitter, which are key issues in communications and consumer electronics design. The new devices offer 3.3-V and 2.5-V operation, enabling designers to migrate seamlessly to a 2.5-V supply as system needs dictate.
The LVDS20 and LVP20 join TI's portfolio of products supporting the LVDS and LVPECL standards, including the LVDS16/17/18/19 and LVP16/17/18/19 high gain output oscillator buffers. For more information about TI's complete line of interface products that empower designers to differentiate their products and accelerate time-to-market, please see the new Interface Selection Guide at interface.ti.com.
