CDCU2A877 Datasheet 1.8-v Phase Lock Loop Clock Driver

Manufacturer: Texas Instruments

Overview: www.ti.com CDCU2A877 SCAS827A – AUGUST 2006 – REVISED JUNE 2007 1.

General Description

The CDCU2A877 is a high-performance, low-jitter, low-skew, zero-delay buffer that distributes a differential clock input pair (CK, CK) to 10 differential pairs of clock outputs (Yn, Yn) and to one differential pair of feedback clock outputs (FBOUT, FBOUT).

The clock outputs are controlled by the input clocks (CK, CK), the feedback clocks (FBIN, FBIN), the LVCMOS control pins (OE, OS), and the analog power input (AVDD).

When OE is low, the clock outputs, except FBOUT/FBOUT, are disabled while the internal PLL continues to maintain its locked-in frequency.

Key Features

  • 1.8-V/1.9-V Phase Lock Loop Clock Driver for Double Data Rate ( DDR II ).
