IDTCV149 PROGRAMMABLE FLEXPC™ CLOCK FOR AMD K8 PROCESSOR ATI RS480 COMMERCIAL TEMPERATURE RANGE IDTCV149 PROGRAMMABLE FLEXPC™ CLOCK FOR AMD K8 PROCESSOR ATI RS480 FEATURES: DESCRIPTION: • One high precision N and SSC programmable PLL for CPU • One high precision N and SSC programmable PLL for SRC[2:1] • One high precision N and SSC programmable PLL for SRC0 [7:3] (PCI Express) • One high precision PLL for 48MHz • Band-gap circuit for differential outputs • Support multiple spread spectrum modulation, down and center • Support SMBus block read/write, index read/write • Selectable output strength for REF, PCI, 48MHz, HTT66 • Available in SSOP and TSSOP packages IDTCV149 is a 56 pin clock device for AMD advance K8 processors. The CPU output buffer is designed to support up to 400MHz processor. This device also implements Band-gap referenced IREF to reduce the impact of VDD variation on differential outputs, which can provide more robust system performance. Each CPU/SRC clock has its own Spread Spectrum selection, which allows for isolated changes instead of affecting other clock groups. KEY SPECIFICATION: • CPU CLK cycle to cycle jitter < 85ps • SRC CLK cycle to cycle jitter < 100ps • Static PLL frequency divide error = 0 ppm FUNCTIONAL BLOCK DIAGRAM SRC SSC N Programming SRC[7:3], 0 SRC PCI0 PCI/ SRC PLL SSC N Programming 14.318MHz Osc SRC/ CLKREQ0# CLKREQ1# CPU PLL SSC N Programming Host/ Fixed PLL No SSC 48MHz/ SRC[2:1] CPU[1:0] HTT66 TURBO1# USB48 24_48MHz REF[2:0] Reset# OUTPUT TABLE CPU CLKREQ SRC HTT66 PCI TURBO USB48 24_48 REF RESET# 2 2 8 1 1 1 1 1 3 1 The IDT logo is a registered trademark of Integrated Device Technology, Inc.

After detecting CLKREQ# de-assertion, all controlled SRC clocks will resume in a glitch free manner. tDRIVE_SRC CLKREQ# SRC SRC# 16 IDTCV149 PROGRAMMABLE FLEXPC™ CLOCK FOR AMD K8 PROCESSOR ATI RS480 COMMERCIAL TEMPERATURE RANGE ORDERING INFORMATION IDTCV XXX Device Type XX Package X Grade Blank Commercial Temperature Range (0°C to +70°C) PV PA PAG Small Shrink Outline Package Thin Shrink Small Outline Package TSSOP - Green 149 Programmable FlexPC™ Clock for AMD K8 Processor ATI RS480 17 IMPORTANT NOTICE AND DISCLAIMER RENESAS ELECTRONICS CORPORATION AND ITS SUBSIDIARIES (“RENESAS”) PROVIDES TECHNICAL SPECIFICATIONS AND RELIABILITY DATA (INCLUDING DATASHEETS), DESIGN RESOURCES (INCLUDING REFERENCE DESIGNS), APPLICATION OR OTHER DESIGN ADVICE, WEB TOOLS, SAFETY INFORMATION, AND OTHER RESOURCES “AS IS” AND WITH ALL FAULTS, AND DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT OF THIRD PARTY INTELLECTUAL PROPERTY RIGHTS.
