23S08T-1DCG8

Overview

The IDT2308T-1DCG8 is a zero-delay clock multiplier and buffer manufactured by Renesas Electronics Corporation (formerly Integrated Device Technology). It operates at a core voltage of 3.3V with an input frequency range of 10 MHz to 133 MHz. The device features one LVCMOS input and eight LVCMOS outputs organized into two banks. Key electrical parameters include a maximum cycle-to-cycle jitter of 200 ps and an output skew of 200 ps. It utilizes a 16-pin SOIC package with a pitch of 1.27 mm and supports commercial temperature ranges from 0°C to 70°C.

Feature Summary

• Zero-delay phase alignment between input reference clock and output clocks
• Eight LVCMOS outputs distributed across two independent banks
• Supports spread spectrum input for EMI reduction
• Low power consumption with tri-state capability in power-down mode

Applications

• High-speed clock distribution networks
• System synchronization in data communication equipment
• Clock multiplication for processors and memory interfaces

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging, as standard variants often use tubes. Confirm the exact multiplier configuration (1x vs 2x) against the official datasheet, as the base model number may imply different internal prescaling options. Ensure the component status is checked, as older IDT parts may be obsolete or subject to last-time buys.

Selection Notes

Select this component when low jitter (<200 ps) and precise phase alignment are required for single-source clock distribution. Verify that the 3.3V LVCMOS output levels match the receiving logic inputs. Consider the SOIC package dimensions if board space is constrained compared to TSSOP alternatives.

Part Context

This part belongs to the IDT 2308 family of high-speed PLL clock multipliers. The 'DCG8' suffix denotes the 16-lead SOIC package type. The 'T' typically signifies tape-and-reel shipping format. This family is designed for applications requiring flexible clock multiplication and distribution without external feedback components.

Replacement Considerations

Direct pin-compatible replacements within the same family include the IDT2308-1DCG8 or IDT2308-2DCG8, depending on the required multiplication factor. Verify that any substitute maintains the same 3.3V supply requirement and LVCMOS output drive characteristics.
