ICS307

Part: ICS307-01 / ICS307-02 — Integrated Device Technology (IDT)

Type: Serially Programmable Clock Source

Description: Serially programmable clock generator with 6–200 MHz output on CLK1 and a second configurable output (CLK2), 5–27 MHz crystal input, 3.3 V or 5 V operation, and lock to a new frequency in 10 ms or less.

Operating Conditions:

• Supply voltage: 3.0–5.5 V
• Operating temperature: 0 to +70 °C (commercial); -40 to +85 °C (industrial version)
• Crystal input frequency: 5–27 MHz; clock input: 2–50 MHz
• Output frequency: 6–200 MHz (6–180 MHz for industrial version)

Absolute Maximum Ratings:

• Max supply voltage (VDD): 7 V
• Input/output voltage: -0.5 V to VDD+0.5 V
• Storage temperature: -65 to +150 °C
• Soldering temperature: 260 °C

Key Specs:

• Output low voltage: 0.4 V max at IOL = 25 mA
• Operating supply current: 26 mA typ (20 MHz crystal, no load, 100 MHz output); 13 mA typ (100 MHz output, 3.3 V)
• Short circuit current: ±70 mA typ
• Output rise/fall time: 1 ns typ (15 pF load)
• Output duty cycle: 45–55% (even output divides); 40–60% (odd output divides)
• Jitter: 50 ps one-sigma clock period jitter typ; ±120 ps maximum absolute jitter typ
• Power-up time: 3 ms typ, 10 ms max (STROBE high to clock output)
• Serial programming: SCLK up to 50 MHz; 24-bit word via 3-wire interface (DATA, SCLK, STROBE)
• Thermal resistance θJA: 120 °C/W (still air)

Features:

• Packaged in 16-pin (150 mil) SOIC; Pb-free versions available
• Serially programmable via a 3-wire interface
• Eliminates the need for custom quartz
• Power-down tri-state mode via PDTS pin
• Very low jitter
• Operates from 3.3 V or 5 V
• 25 mA drive capability at TTL levels
• ICS307-02 powers up with a default x1 output on CLK1 and CLK2 and is recommended for new designs
• Industrial temperature version available
• Smooth frequency transitions when the output divider is unchanged

Applications:

• General clock generation
• Replacement for custom crystals or oscillators

Package:

• 16-pin SOIC (150 mil narrow body)

This product is intended for clock generation. It has low output jitter (variation in the output period), but input to output skew and jitter are not defined nor guaranteed. For applications which require defined input to output skew, use the ICS527-01.

Stresses above the ratings listed below can cause permanent damage to the ICS307-01/-02. These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
