What are the key features of CDCV857BDGGG4?

  • PLL-based clock driver with 10 true 3-state outputs for precise, low-skew clock tree distribution
  • Differential input conditioning supports LVPECL, LVDS, or single-ended clock sources without external components
  • 48-pin TSSOP package enables high-density board placement in multi-load clock fan-out designs

What is CDCV857BDGGG4 used for?

CDCV857BDGGG4 is used in high-speed digital systems such as networking switches, server motherboards, and FPGA development boards where a single reference clock must fan out to 10 synchronous loads with minimal skew. Its PLL architecture removes reference jitter and regenerates clean clock edges for DDR memory controllers, ASICs, and bus bridges. The 3-state output feature allows multiple drivers on a shared clock bus for testability and power management.

Frequently Asked Questions

How many outputs does CDCV857BDGGG4 support, and what output drive current does each provide?

CDCV857BDGGG4 features 10 true clock outputs, each with a maximum output low current (I_OL) of 12 mA. The 3-state control on all outputs allows individual enable/disable for power saving or bus-sharing configurations. This combination of fan-out count and drive strength suits multi-load clock distribution in DDR, FPGA, and ASIC subsystems.

What input clock formats does CDCV857BDGGG4 accept, and how does the PLL improve signal quality?

CDCV857BDGGG4 accepts differential input clock signals, including LVPECL and LVDS formats, through its differential input conditioning stage. The internal PLL multiplies and regenerates the reference clock, reducing input jitter and producing clean 3-state output edges. This makes it suitable for systems requiring sub-100 ps cycle-to-cycle jitter at output frequencies up to several hundred MHz.

What board space does the 48-pin TSSOP package of CDCV857BDGGG4 occupy compared to larger packages?

The 48-pin TSSOP (JESD-30 code R-PDSO-G48) has a body width of approximately 6.1 mm and a pin pitch of 0.5 mm, making it significantly more compact than equivalent 48-pin SOIC packages. This small footprint allows CDCV857BDGGG4 to fit within tight PCB areas on server backplanes or mid-sized networking cards while still routing 10 differential output pairs.

Is CDCV857BDGGG4 RoHS compliant, and what is its recommended alternative if it reaches end-of-life?

CDCV857BDGGG4 carries JESD-609 Code e4, indicating lead-free (RoHS-compliant) termination for all 48 pins. Designers evaluating end-of-life risk should check TI's CDCV857B family for active replacement parts, as the YTEOL value of 0 signals this part may be at or near end of product lifecycle. Stocking safety inventory of at least 12 months of demand is advisable.
