Product details

133 MHz clock multiplier, no PLL — what that means for your board

The W194-70G is a frequency multiplier and zero delay buffer. Maximum output frequency is 133 MHz with a 2:2 input-to-output ratio, operating from 0°C to 70°C.

Dual supply range: 3.3V or 5V

The supply voltage range covers both 3.3V nominal (3.135V–3.465V) and 5V nominal (4.5V–5.5V), so the same part can be used in a 3.3V core logic board or a legacy 5V peripheral bus. No external level translation needed on the supply.

RoHS non-compliant — legacy finish

The W194-70G is RoHS non-compliant with a lead-bearing finish.

Package and footprint

Housed in an 8-pin SOIC (0.154" body width, 3.90 mm pitch), surface-mount. The 8-SOIC footprint is a standard, hand-solderable package — easy to prototype on a breakout board or integrate into a production PCB. No exposed pad, no thermal vias needed.

Frequently asked questions

What is the function of W194-70G?

The W194-70G is a PLL-based clock driver that functions as a frequency multiplier and zero delay buffer. It takes an input clock and outputs a multiplied copy with minimal delay, without the lock-time of a PLL.

Is W194-70G RoHS compliant?

No, the W194-70G is marked RoHS non-compliant, indicating a lead-bearing finish. This is acceptable in applications with a RoHS exemption or where tin-lead solder is preferred.

What is the equivalent of W194-70G?

A functional peer is the CY2305SXI-1HT, which is a PLL-based zero delay buffer with a 1:5 fanout and a wider -40°C to 85°C temperature range. The CY2305 includes a PLL, so it offers phase lock but adds lock-time and jitter compared to the W194-70G's PLL-free multiplier topology.
