CLOCK FOR P4 PROCESSOR
IDTCV122C
FEATURES:
One high precision N Programming PLL for CPU
One high precision N Programming PLL for SRC/PCI
One high precision PLL for SATA
One high precision PLL for 96MHz/48MHz
Band-gap circuit for differential outputs
Support multiple spread spectrum modulation, down and
center
• Support I

C block read/write, index read/write
• Selectable output strength for REF, PCI, and 48MHz
• Available in SSOP package
DESCRIPTION:
IDTCV122C is a 56 pin clock device, complying the latest Intel CK410
requirements, for Intel advance P4 processors. The CPU output buffer is
designed to support up to 400MHz processor. One dedicated PLL for Serial
ATA clock provides high accuracy frequency. This device also implements
Band-gap referenced I
REF
to reduce the impact of V
DD
variation on differential
outputs, which can provide more robust system performance.
Each CPU/SRC/PCI, SATA clock has its own Spread Spectrum selection,
which allows for isolated changes instead of affecting other clock groups.
KEY SPECIFICATION:
• CPU/SRC CLK cycle to cycle jitter < 85ps
• SATA CLK cycle to cycle jitter < 85ps
• Static PLL frequency divide error = 0 ppm
Not recommended for new designs.
The last time buy for this product is 12/17/2010.
Please refer to PDN K-10-15.
