P0024-02 CDCP1803 www.ti.com SCAS727F – NOVEMBER 2003 – REVISED DECEMBER 2013 1:3 LVPECL CLOCK BUFFER WITH PROGRAMMABLE DIVIDER Check for Samples: CDCP1803 1 FEATURES • Distributes One Differential Clock Input to Three LVPECL Differential Clock Outputs • Programmable Output Divider for Two LVPECL Outputs • Low-Output Skew 15 ps (Typical) • VCC Range 3 V–3.6 V • Signaling Rate Up to 800-MHz LVPECL • Differential Input Stage for Wide Common- Mode Range • Provides VBB Bias Voltage Output for Single- Ended Input Signals • Receiver Input Threshold ±75 mV • 24-Terminal QFN Package (4 mm × 4 mm) • Accepts Any Differential Signaling: LVDS, HSTL, CML, VML, SSTL-2, and Single-Ended: LVTTL/LVCMOS DESCRIPTION The CDCP1803 clock driver distributes one pair of differential clock inputs to three pairs of LVPECL differential clock outputs Y[2:0] and Y[2:0] with minimum skew for clock distribution. The CDCP1803 is specifically designed for driving 50- Ω transmission lines. The CDCP1803 has three control terminals, S0, S1, and S2, to select different output mode settings; see Table 1 for details. The CDCP1803 is characterized for operation from –40°C to 85°C. For use in single- ended driver applications, the CDCP1803 also provides a VBB output terminal that can be directly connected to the unused input as a common-mode voltage reference. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
