| Micrel, Inc. 3.3V DUAL DIFFERENTIAL LVPECL-TO-LVTTL TRANSLATOR Precision Edge SY89323L Precision Edge(R) SY89323L (R) FEATURES 3.3V power supply 1.9ns typical propagation delay Maximum frequency > 275MHz Differential LVPECL inputs 24mA LVTTL outputs Flow-through pinouts Internal input resistors: pull-down on IN, pull-down and pull-up on /IN Q output will default LOW with inputs open Available in ultra-small 8-pin MLF(R) (2mm x 2mm) package Precision Edge(R) DESCRIPTION The SY89323L is a dual differential LVPECL-to-LVTTL translator. Because LVPECL (Low Voltage Positive ECL) levels are used, only +3.3V and ground are required. The SY89323L is functionally equivalent to the SY100EPT23L, but in an ultra-small 8-pin MLF(R) package that features a 70% smaller footprint. The ultra-small package and the dual gate design of the SY89823L make it ideal for applications that require the translation of a clock and data signal in a minimal space. The inputs are compatible with 10k and 100k input levels and any standard differential LVPECL input referenced to a VCC of 3.3V.

If left open, pin defaults LOW. Q output will be LOW. See "Input Interface Applications" section for single-ended inputs. Differential PECL/ECL Input: Internal 75k pull-up and pull-down resistors. If left floating, pin defaults to VCC/2. When not used, this input can be left open. See "Input Interface Applications" section for single-ended inputs. Single-ended LVTTL Outputs: Default to LOW if IN inputs left open. Positive Power Supply: Bypass with 0.1F//0.01F low ESR capacitors. GND and exposed pad must be tied to ground plane. 2, 3 /IN0, /IN1 ECL Input 7, 6 8 5 Q0, Q1 VCC GND, Exposed Pad LVTTL Output VCC Power Ground M9999-051006 hbwhelp@micrel.com or (408) 955-1690 2 Micrel, Inc.

Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratlng conditions for extended periods may affect device reliability. 2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings. 3. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the devices most negative potential on the PCB. 4. VIHCMR (min) varies 1:1 with VEE, max varies 1:1 with VCC.
