IDTCSPU877ABV

The IDTCSPU877ABV is designed as a PLL based clock driver that acts as a zero delay buffer to distribute one differential clock input pair to 10 differential output pairs and one differential pair of feedback clock output. External feedback pins of IDTCSPU877ABV for synchronization of the outputs to the input reference is provided. OE, OS and Avdd control the power-down and test mode logic.

IDTCSPU877ABV has eleven features. (1)1 to 10 differential clock distribution. (2)Optimized for clock distribution in DDR2 (douple data rate) SDRAM applications. (3)Operating frequency would be from 125MHz to 270MHz. (4)Very low skew <=40ps. (5)Its very low jitter <=40ps. (6)1.8V AVdd and 1.8V Vddq. (7)CMOS control signal input. (8)Test mode enables buffers while disabling PLL. (9)Low current power-down mode. (10)Tolerant of spread spectrum input clock. (11)Available in 52-ball VFBGA and 40-pin MLF packages. Those are all the main features.

Some absolute maximum ratings have been concluded into several points of IDTCSPU877ABV as follow. (1)Its supply voltage range would be from -0.5V to 2.5V. (2)Its input voltage range would be from -0.5V to Vddq+0.5V. (3)Its voltage range applied to any output in the high or low state would be from -0.5V to Vddq+0.5V. (4)Its input clamp current would be +/-50mA. (5)Its output clamp current would be +/-50mA. (6)Its continuous current would be +/-50mA. (7)Its continuous current would be +/-100mA. (8)Ts storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of IDTCSPU877ABV are concluded as follow. (1)Its input clamp voltage all inputs would be max -1.2V. (2)Its input low voltage would be max 0.35Vddq. (3)Its input high voltage would be min 0.65Vddq. (4)Its input signal voltage would be min -0.3V and max Vddq+0.3V. (5)Its DC input differential voltage would be min 0.3V and max Vddq+0.4V. (6)Its output differential voltage would be min 0.5V. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
