Product details
Overview
2305NZ-1HDCGI8 from Renesas Electronics is a 3.3V five-output clock buffer IC designed for high-speed clock distribution in mobile and desktop PC systems. It supports DC to 133.33MHz operation, delivers ≤8.7ns input-to-output propagation delay, maintains <250ps output-to-output skew, and draws ≤35mA at 66.66MHz with unloaded outputs.
For engineers reviewing the 2305NZ-1HDCGI8 datasheet, 2305NZ-1HDCGI8 pinout, 2305NZ-1HDCGI8 application, or 2305NZ-1HDCGI8 equivalent, key selection criteria include industrial temperature range (–40°C to +85°C), SOIC-8 package compatibility, low EMI design, and precise timing integrity across five synchronized outputs.
Technical Context
The 2305NZ-1HDCGI8 implements a single-input, five-output CMOS buffer architecture optimized for clock fanout without phase inversion. Its input threshold is VDD/2, and all outputs are rail-to-rail compatible with 3.3V supply, supporting both commercial (0°C to +70°C) and industrial (–40°C to +85°C) ambient ranges.
It guarantees ≤1.5ns rise/fall times (measured 0.8V–2V), 45%–55% duty cycle stability at VDD/2, and operates with load capacitance up to 30pF below 100MHz and 15pF up to 133.33MHz - enabling reliable signal integrity in dense PCB layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar clock buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ICS553M-01ILF | 3.3V, 5-output, but max frequency 100MHz; higher typical IDD (42mA) | Limited to sub-100MHz designs; not suitable for 133.33MHz DDR or PCIe clocking | Select when lower cost is prioritized over max frequency and skew performance |
| PI6C20400LEX | 3.3V, 4-output, LVCMOS; max frequency 200MHz; output skew <150ps | One fewer output; tighter skew spec but requires layout adaptation for 4-output routing | Choose for higher-frequency or ultra-low-skew requirements where output count can be reduced |
Compared with ICS553M-01ILF and PI6C20400LEX, the 2305NZ-1HDCGI8 uniquely balances five-output capability, 133.33MHz bandwidth, industrial temperature support, and sub-250ps skew - making it optimal for space-constrained, thermally demanding PC and industrial timing applications requiring exact output count and proven reliability.

FAQ
What is the maximum operating frequency supported by the 2305NZ-1HDCGI8?
The 2305NZ-1HDCGI8 supports clock frequencies from DC up to 133.33MHz, as specified in both commercial and industrial operating conditions. This allows use in DDR memory interfaces, USB 2.0 root hubs, and legacy PCI Express Gen1 clock trees. The device maintains guaranteed timing parameters - including propagation delay and skew - across this full range when operated within its 3.0V–3.6V supply and specified load capacitance limits.
Does the 2305NZ-1HDCGI8 require external termination resistors?
No, the 2305NZ-1HDCGI8 does not require external termination resistors for standard CMOS loads. Its outputs are designed to drive typical capacitive loads up to 30pF (for frequencies <100MHz) or 15pF (up to 133.33MHz) directly. Per the datasheet test circuit, only a 0.01µF decoupling capacitor on VDD (pin 6) is mandatory. External series resistors may be added for impedance matching in specific high-speed routing scenarios, but they are not inherent to basic functionality of the 2305NZ-1HDCGI8.
What is the meaning of "-1HDCGI8" in the part number 2305NZ-1HDCGI8?
The suffix "-1HDCGI8" denotes: "1" = standard speed grade; "HD" = 8-pin SOIC package; "CG" = Pb-free/RoHS-compliant; "I" = industrial temperature range (–40°C to +85°C); "8" = tape-and-reel packaging. This distinguishes it from commercial-grade variants like 2305NZ-1HDCG8 (0°C to +70°C) and tube-packaged versions. All share identical electrical and timing behavior - only packaging and qualification differ.
Can the 2305NZ-1HDCGI8 be used with 2.5V or 1.8V logic families?
No, the 2305NZ-1HDCGI8 is strictly a 3.3V-only device: its VDD must be between 3.0V and 3.6V, and its outputs swing rail-to-rail within that range. It is not 5V-tolerant nor level-shiftable. Interfacing with 2.5V or 1.8V logic requires external level translation. The input threshold is fixed at VDD/2 (~1.65V), so direct connection to lower-voltage drivers violates VIH/VIL specifications and risks unreliable switching or increased power consumption in the 2305NZ-1HDCGI8.
How is output skew measured for the 2305NZ-1HDCGI8, and why is it important?
Output skew for the 2305NZ-1HDCGI8 is measured as the maximum time difference between rising (or falling) edges of any two outputs under equal loading conditions, and is guaranteed ≤250ps. This parameter is critical in applications like parallel data buses or multi-channel ADC sampling, where simultaneous clocking ensures deterministic sampling alignment. Exceeding this skew can cause timing violations, metastability, or data corruption - especially at high frequencies where nanosecond-level margins dominate system timing budgets.
