No 5245 manuals on Agilent site nor the agilent ftp site nor BAMA site. The HP5370A also used a 10544A as an optional high stability timebase OCXO. The reference buffer PCB is close to the 10544A socket. The reference buffer consists of a series string of 3x 1/3 MC10216 ECL line receivers. The reference input pin uses a 1k resistor in series with 10pF connected to the input of the first ECL line receiver. This buffer is somewhat crude, but nevetheless has adequate performance for its intended application.
