TI introduces the industry’s smallest sine-to-sine wave clock buffer

Highly integrated clock buffer reduces cost and board space

Bangalore (November 26, 2009) – Texas Instruments Incorporated (TI) today introduced the industry’s smallest four-channel, low-power, low-jitter sine-to-sine wave clock buffer, the first device in a family of sine-wave clock buffers. The CDC3S04 can replace up to three individual same-frequency temperature compensated crystal oscillators (TCXOs), reducing board space and bill of materials (BOM) by nearly half. Designers can use the CDC3S04 in a wide range of mobile applications including cell phones (UMTS/WCDMA/GSM), smartphones, mobile internet devices (MID), ultra mobile PCs (UMPC), navigation units and global positioning systems (GPS). Download the datasheet and order samples here: www.ti.com/cdc3s04-pr1.   

Key features and benefits of the CDC3S04:

• 1:4 low-jitter, sine-to-sine clock buffer replaces multiple TCXOs, saving board space and cost
• An integrated on-chip LDO saves board space by eliminating the need for an internal low-dropout (LDO) regulator.
• The on-chip LDO acts as a TCXO on/off switch for power savings during low-power standby
• This buffer distributes sine-wave signals to four different peripherals while adding negligible phase-noise, minimizing electromagnetic interference (EMI).
• A built-in I2C interface gives customers real-time control for outputs, polarity and internal coding.
• Designers can accelerate time-to-market by taking advantage of TI’s OMAP4xx processors.
