3.3V/5V 2.5GHz PECL/ECL DIFFERENTIAL RECEIVER/BUFFER Micrel, Inc. Precision Edge® SY89306/316V ® Precision Edge SY89306/316V FEATURES ■ ■ ■ ■ ■ ■ fMAX > 2.5GHz Inputs (D, /D) include 75kΩ pull-down resistors SY89306V: 100k EP compatible SY89316V: 10k EP compatible Industrial temperature range: –40°C to +85°C Available in an ultra-small 8-pin (2mm × 2mm) MLF® package Precision Edge® DESCRIPTION The SY89306V and SY89316V are a high-speed buffer/ receivers. The devices are functionally equivalent to the 10/100EP16 buffers, but feature a 70% smaller footprint. The SY89306/316V includes a VBB reference for singleended AC-coupling applications. Whenever used, the VBB pin should be bypassed to ground via a 0.01µF capacitor. VBB reference can only sink/source 0.5mA. Under open input conditions (pulled to VEE), internal input clamps will force the Q output LOW.
