Sine-to-Sine Wave Clock Buffer conserves board space.

Press Release Summary:

Supplied in 1.6 x 2.0 mm-footprint WCSP, 4-channel CDC3S04 can replace up to 3 individual same-frequency TCXOs and is suited for mobile applications. It distributes sine-wave signals to as many as 4 different peripherals while adding negligible phase-noise, minimizing EMI. Built-in I²C interface gives real-time control for outputs, polarity, and internal coding, while integrated on-chip LDO acts as TCXO on/off switch for power savings during low-power standby.

TI Introduces the Industry's Smallest Sine-to-Sine Wave Clock Buffer

Highly integrated clock buffer reduces cost and board space

DALLAS, Nov. 24 -- Texas Instruments Incorporated (TI) (NYSE: TXN) 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).

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.

Availability and pricing

The CDC3S04 is in volume production today, and evaluation modules (EVMs) will be available in late 4Q09. The CDC3S04 comes in an industry-leading, small-footprint WCSP package (1.6 mm x 2.0 mm), and is priced at $1.80 in 1,000-unit quantities.
