Microchip Technology

The SY89321L is a differential LVPECL/CML/LVDSto-LVTTL translator requiring only a single +3.3V power.The SY89321L is functionally equivalent to the SY100EPT21L, but in an ultra-small 8-pin MLF® package that features a 70% smaller footprint. This ultra-small package and low skew single gate design make the SY89321L ideal for applications that require the translation of a clock or data signal where minimal space, low power and low cost are critical.VBB allows a differential, single-ended, or AC-coupled interface to the device. If used, the VBB output should be bypassed to VCC with 0.01µF capacitor.Under open input conditions, the /IN will be biased at a VCC/2 voltage level and the IN input will be pulled to ground. This condition will force the Q output low to provide added stability.The SY89321L is compatible with positive ECL 100k logic levels.

The SY89322V is a dual TTL/CMOS-to-differential PECL translator capable of running from a 3.3V or 5V supply. This part can be used in either LVTTL/LVCMOS/LVPECL or TTL/CMOS/PECL systems. It requires only a single positive supply of +3.3V or +5V, no negative supply is required.The SY89322V is functionally equivalent to the SY100EPT22V, but in an ultra-small 8-lead MLF® package that features a 70% smaller footprint. The ultra-small package and the low skew, dual gate design of the SY89322V makes it ideal for those applications where space, performance and low power are at a premium.

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® 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.

The SY89325V is a fully differential, CML/PECL/LVPECLto-LVDS translator. It achieves LVDS signaling up to 1.5Gbps and clock rates of 750MHz, depending of the distance and the characteristics of the media and noise coupling sources. LVDS is intended to drive 50Ω impedance transmission line media such as PCB traces, backplanes, or cables.SY89325V inputs can be terminated with a single resistor between the true and complement pins of the input.The SY89325V is a member of Micrel's Precision Edge® family of high-speed logic devices. This family features ultra-small packaging, high signal integrity, and operation at many different supply voltages. For applications that require dual translators, consider the SY55855V.

The SY89328L is a differential LVPECL-to-LVTTL translator and an LVTTL-to-differential LVPECL translator in a single package. Because LVPECL (Positive ECL) levels are used, only +3.3V and ground are required. The SY89328L is functionally equivalent to the SY100EPT28L, but in an ultra-small 8-lead MLF™ package that features a 70% smaller footprint. This ultra-small package and the dual translation design of the SY89328L make it ideal for applications that are sending and receiving signals across a backplane.
