DallasTexas Instruments Inc. has introduced a 4-Gbits/s low-voltage differential signaling (LVDS) and low-voltage pseudo emitter-coupled logic (LVPECL) repeater and translator.
Featuring low total jitter of 45-ps, the SN65LVDS20 and SN65LVP20 devices help ensure signal and clock integrity in various communications applications, such as high-speed network routing, wireless base stations and 622-MHz central office clock distribution. They can also serve as translators in many consumer applications.
The SN65LVDS20 and SN65LVP20 connect a high-speed differential receiver and driver as a repeater, which accepts low-voltage PECL signals at rates up to 4-Gbits/s and repeats them as LVDS (LVDS20) or LVPECL (LVP20) output signals. The differential signal path through the devices minimizes EMI and limits added jitter.
The SN65LVDS20 and SN65LVP20 devices offer 3.3-V and 2.5-V operation, which enables designers to easily migrate to a 2.5-V supply. They also feature 120-ps output transition times; less than 630-ps propagation delay times; and a supply current of less than 42-mA.
The devices are available now in volume from TI's authorized distributors. They are packaged in an 8-pin, 2-mm X 2-mm X-0.75-mm lead-free small-outline, no-lead package (SON). In 1,000-piece quantities, the LVDS20 is priced at $3.30 each and the LVP20 costs $4.40 each. Samples are available for 24-hour delivery.
