Quantity / Special Request

Please specify the quantity you require below.

The GVXO-E33L is supplied on tape and reel. 2k pcs per reel is the standard T&R pack size for this product. Partial quantities may be supplied on tape (no reel), or in bulk.

Product Description

The multiplier-free design of the GVXO-E33L allows for exceptionally good phase jitter performance of just 1ps max (frequency dependent).

Available up to 250MHz, this voltage controlled oscillator has been designed specifically for use within applications focused on high speed data transfer including high speed wireless communications, telecoms, network systems, computing and instrumentation.

The GVXO-E33L is available in a miniature 3.2 x 2.5mm ceramic package and also features a choice of frequency stability and pullability options. With complementary PECL output, and requiring 3.3V supply voltage, this VCXO is suitable for a wide range of data transfer applications.
