Texas Instruments expands its precision timing portfolio with industry’s most highly integrated clock generator family

April 23, 2009

Compact clocking solutions save up to 50 percent board space

DALLAS, April 23 /PRNewswire/ — Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced three new precision clock generators that have a crystal input, replacing up to four discrete high-frequency crystal oscillators with a single device. These devices provide a more cost-efficient solution that saves up to 50 percent more board space than competing solutions today. The CDCM61004 family improves system performance by achieving integrated RMS jitter of 500 fs, well suited for data communications equipment. For product details and to order samples see: www.ti.com/cdcm61004-pr.

The CDCM61004 family eases board design by providing a fully integrated voltage-controlled oscillator (VCO) support for a wide output frequency range from 43.75 MHz to 683 MHz, allowing one device to cover multiple standards or multiple designs. The clock generators operate at less than 500 mW to enable high-density designs, offering up to 30 percent power savings.

Key Features

  • Input reference including the commonly used crystal frequencies such as 24.8832 MHz, 25 MHz, and 26.5625 MHz
  • On-chip VCO operates in frequency range 1.75 GHz to 2.05 GHz, supporting output from 43.75 MHz to 683 MHz
  • Input crystal bypass mode allows direct tuning on the reference
  • Output selectable between LVPECL, LVDS or 2-LVCMOS

Key Benefits

  • Pin-compatible family allows the same hardware strapping
  • High integration and flexible I/O minimizes the number of components
  • Reduces board space and provides a cost-efficient solution
  • Low jitter improves overall system bit error rate performance
  • Low power enables high-density designs

Availability and pricing

The CDCM61004 family is available now in volume production in a QFN-32 package. The CDCM61004 has four LVPECL/LVDS or eight LVCMOS outputs and is priced at $8.15. The CDCM61002 has two LVPECL/LVDS or four LVCMOS outputs and is priced at $6.25. The CDCM61001 has one LVPECL/LVDS or two LVCMOS outputs and is priced at $5.25. All pricing is in quantities of 100 units.
