SK1300 PECL / LVPECL to LVDS Translator HIGH PERFORMANCE PRODUCTS Description The SK1300 is a high speed PECL / LVPECL to LVDS translator. This device is designed to support frequency rates in excess of 800 MHz utilizing low voltage differential signaling (LVDS) technology. SK1300 operates over an extended supply range of 3.0 to 5.5V which allow either PECL or LVPECL signal at its inputs based on the supply voltage range. It also provides a new alternative to high power pseudo-ECL devices for high speed point-to-point interface using LVDS type signals. The SK1300 provides a VBB outputs for either singleended use or as a DC bias for AC coupling to the device. The VBB output should only be used as a bias for the SK1300 as its current sink/source capability is limited. Whenever used, the VBB output should be bypassed to VCC via a 0.01 mF capacitor. Under open input condition, the pulldown on D and pullup and pulldown on D* will force the Q output low and Q* output high.

DVOUT is obtained as follows: Voltages of Q and Q* outputs with respect with VEE are measured. The absolute difference between the high and the low is equal to DVOUT. CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the high level falls within the specified range and the peak-to-peak voltage lies between VPP(min) and 1V. The lower end of the CMR range varies 1:1 with VEE and is equal to VEE + 1.7V. 250 mV minimum output peak-to-peak swing for Max Toggle Frequency. Output test conditions: 100W termination resistor between Q and Q*.
